YES

"unhandled" - handled by DKRNL32 instead HDPMI32 ?

I didn't terminate the host the "hard way" - the problem occurs after an application crashed in DKRNL32 or DGDI32 and was terminated by DKRNL/DPMILD for this. Drops back to DOS, all seems OK, one can even uninstall/reinstall mouse driver (it "helps" ), but if I touch the mouse without "fixing" the driver before, the GPF in Ring 0 occurs - then "terminate s/erver" offer appears, but it's too late: either no reaction to keypress at all, or some garbage is reported then (low mem corruption ?) - freezer, reboot

Does this mean the problem is unfixed and not easy to fix ?
