Subject: Graphics not working with DJGPP upgrade

I used djdev107, djgas138, djgcc222 and cbgrx102 and everything worked
beautifully.

I upgraded to djdev110, gas211bn and gcc241bn, recompiled libgrx with the new
compiler and now nothing works at all for graphics.

I can't even get the sample program that uses only libgr.a (with "tasks") to 
work, it crashes the system (requiring hardware reset).

Running debug32 usually crashes out but sometimes crashes at some weird address
before main() has started.

I wrote a 3 line program that set default graphics mode, did a getch(), then
went back to text mode. This ran but didn't go to graphics mode (ie it accepted 
a keypress but returned to dos without changing video modes).

Most of the libgrx demos hang the system, but some put the display into weird
graphics modes (unreadable).

Any clues? Email replies please.

thanks
