System Hang when using CRT unit

If i run a TP program under Win95 by using 'Start | Run', or
by clicking on it's icon in explorer, the dos window opens,
and the computer totally locks up (hard reset needed).

The problem does not occur if i run the program from
a dos window (when the window is already opened).

This happens with program's that use the CRT unit as
i have compiled programs without the CRT unit and they
work fine.

I am using TP7, with a Cirrus PCI Graphics Card with
Win95 (Service Pack 1).

I think this is related to the graphics card, as i don't
remember having this problem with my old card (ISA).

I have tested programs on other machines, and these
all work fine.

Has any one else had this problem??

Greetings,
              Is your computer fast? (over 100 Mhz), this may be the problem,
because there is a bug in the CRT unit with delay. Check this web page out,
it has a patch to fix the problem:

The manual patch is also available on my web page.
