CPU usage problem with the mouse

2005-02-21 09:41 am

If you select notes with the mouse and don't release the button, you'll notice the CPU usage goes to 100%. After you release the button, the CPU usage goes back down.

Why isn't anyone answering?

a/ because nobody was online between the time of the posting and now, or

b/ because nobody wrote a question.

If a response is desired, it should be made clear. Otherwise it just looks like a statement of opinion or fact.

Besides, why respond to people who don't give their names?

I was expecting someone to comfirm the problem...

It would be a good idea to say so. Other users can't read your mind.

Hope you're having a good summer.

Summer!!! It's almost the middle of Winter here - I had to scrape ice off all 12 car windows this morning - then I had to do the windscreen again, as it was already starting to ice up again!

Cheers from sunny, but icy, Canberra!

Hi Ewan,
Canberra eh, I'll be passing through about 5 AM on Saturday, on my way to [abbr=All my kids are grown up, so I can finally afford such an indulgence]2 weeks[/abbr] in the snow - ah, what bliss, what fun, what sore muscles!

I knew it was winter in Australia, Ewan, but I didn't realize you had real winters with snow and ice. Learn something every day!

The snow's mainly restricted to the south-east of the continent - the Australian Alps, but you can get it in elevated places closer to the equator. Toowoomba (west of Brisbane) regularly gets snow. It's unusual to get snow in the flatter, relatively lower, and very broad inland. Probably because it's so dry.

Around the southern coast snow is still rare, although Mount Wellington (which towers above Hobart) always gets snow. Apart from the ski fields, we don't get enough snow in habitable areas to even [abbr=yes, I know it's a split infinitive, but I don't think Latin grammar rules sit well with vernacular English]build[/abbr] a snow-person. We definitely don't get the [abbr=meters, or just read "feet"]metres[/abbr] of snow that sit around for months.

And most of us are grateful.

Why isn't anyone even comfirming if the problem exists or not?

People aren't answering because they obviously aren't finding it to be a problem.

If it is a problem to you, try one of these options:

Stop using your mouse that way.

or

Close the CPU usage indicator.

No problemo, amigo.
Hello from Poland, anyway, where I found that the neighbours have an open wireless Internet connection called 'domek' (at home).

Please comfirm this problem.

to comfirm:
1)open any file in NWC (File->New-><Blank Score> will do)
2)open the Task Manager, or any application that can monitor CPU usage
3)click and hold down the mouse anywhere in the NWC document window
You'll notice that the CPU usage is 100% until release the mouse button...

!you!
I cannot confirm the phenomenon occurs as you state. In my system the CPU usage rises to approx. 55%, not 100%. (Hmm, hyperthreading - both virtual CPUs are reaching the same utilisation - XP is apparently not supporting NWC in an SMP model - makes sense, I don't think NWC has been written with SMP in mind - no reason it should have) I can also state that it does not appear to happen in M$Word 2003, XL2003, Groupwise 6.5, IE 6, notepad, wordpad or calculator.

I cannot confirm that it is a problem. My system behaves just fine whether I hold the mouse button down in NWC or not - the other applications I have running concurrently [and there are always several] do not reflect any kind of performance or other discernable problem.

You are likely just observing an idle loop awaiting a "mouse button up" event that happens to be being detected. Other applications are still generating interrupts and being serviced by the CPU as required. I do not see this as such a big deal. Why do you think it is one?

It could be a bit of an energy consumer when using NWC on a laptop. The processor is busy all the time, goes to a higher energy consumption state, the fan kicks in... all that stuff. The problem is real.
But it is only a matter of concern when the mouse button is down for a longer period... and who needs the mouse more than 1 % of the time in nwc?

G'day Rob,
I take your point, but I'm not sure the CPU utilisation graph is actually [abbr=I've never trusted any CPU utilisation report, whether from Windows, Netware or *nix - none of 'em are dependable in my experience]accurate[/abbr]. We don't really know what it is registering. If it is an idle loop as I suspect then the processor is not actually any busier at all hence the power consumption would not change.

The point is pretty much moot in any case because as you said; there is no need to use the mouse much and even if you did, there is no need to hold a button down for extended periods.

I think there are more relevant enhancements/bug fixes to attend to. This is probably just an artifact from whatever mouse [abbr=probably M$ supplied]library[/abbr] Eric is using.
