---QUOTATION--- Yup, you could create a kill.cmd and throw it into windows directory or something... but for me the procedure does the trick since I usually don't enter commands in the run prompt. ---END QUOTATION---
I tried the following in XP. You might need a program like Explorer running in the background to Alt-Tab to it from the locked-up STALKER.
I put this line in KillSTALKER.cmd on the desktop:
taskkill /F /IM xr_3da.exe
I then right-click-dragged that file and dropped the icon on the desktop. I selected "Create shortcuts here". In the Properties sheet for that shortcut, I set the shortcut key to Ctrl-Alt-End.
From then on, no typing beyond Alt-Tab, Ctrl-Alt-End to kill STALKER.
If you don't want the files cluttering your desktop, you can put the CMD file anywhere, then right-click-drag-drop the file to your Start menu under "All Programs" as a shortcut, then set the shortcut key. This might require a restart.
