Hello, I meet a strange problem : with grx22, I can draw image using GrBitblt function but now, with grx23, this function does nothing . Were there any changements those explain this problem ? What should I do to draw in-memory image to screen now with grx23 ? I'm working on a DOS-based PC with djgpp V2.0, grx23, gcc2.8.1, compiling with -O2 -g -Wall
