I just switched from Windows XP Pro SP3 (32bit) to Windows 7 Ultimate (32bit) on a new PC. Now, both the new onscreen keyboard and a utility for sending mouse clicks are being problematic.

The problem with 7's OSK is that some things I type only work intermittently or just dodgily. Like Alt+Tab with multiple Tabs, other Alt/Ctrl/Shift/Win key combinations, and the context menu key. Sometimes apps will not take focus for input at all. I use the OSK it in 'hover' mode, on 0,5 seconds.

The clicking tool is Point-N-Click, which sends clicks when I dwell anywhere for 1.25 seconds with the mouse pointer. http://www.polital.com/pnc/

The problem with it is that sometimes it fails to click. Most often this happens in some of the control panel sections, on the taskbar, and when UAC pops up. It seems to occur in conjunction with OSK usage a bit too, I think.

I'm using an Administrator account. DEP and UAC settings are default.

What can I do to fix or work around either of these problems? I'm disabled so this really is killing usability.
