Okay, basically, with Num lock on, the arrow keys and the 9 above them (excluding scroll lock and pause/break) do not respond correctly in some programs (register as SHIFT). With Numlock off, they register fine, BUT, in some programs they don't even register. So I wrote a quick program to see that the KeyUp and KeyDown events were returning to the system. With Numlock on, pressing i.e. Right arrow key led to the Keydown event flickering from 'None' to 'Right' and the Keyup event returned a flickering from 'Right' to 'None'. On a friends "normal" computer, each event correctly responded with 'Right'. I noticed this problem at the end of May(!). So I tried to revert my system to as it was before that (BIOS, Chipset drivers, VB.Net and .Net framework etc.) Of course, couldn't revert Windows XP Pro or DX9 back though. So, what on Earth is causing this problem? Is it hardware (I haven't changed any HW since last August), is it a WinXP update, DX9?? I hope someone out there knows!
