Re: NWC2 on Linux/Wine
the tab key navigation is implemented internally by NWC using SetWindowsHookEx(WH_KEYBOARD, ...).
That may explain why they are so hard to drive with SendKeys. Fortunately, if you set up the registry, you can get them to popup with the needed Tabbed page on top. From there, XP and '98 need different techniques. I had to send an initial {Tab} in '98 to get to the same to the state as XP.
This is better left for the 'User Tools' board. I only mention it here as it might bear on the problem.
