Hi list.

I am experiencing a strange problem:

Delphi complain about " PARAMETER IS NOT CORRECT " and
" CANVAS DON'T ALLOW DRAWING " after that it hungs and no way to
resume neither warm boot nor alt+contrl+del.
Only shut off energy works.

This happen just after I have installed the 4.0 Hc demo.
The prog is the same and in previoous version of ibo NO PROBLEM at
all.

Someone want shed light on this??
TIA
TONY
