Error 1285 - gluBuild2DMipmaps failed ?

[madscijr]

The 1285 means OpenGL reported an 'out of memory' error, and that message itself gets thrown if OpenGL fails when creating a new Hardware image (probably for the screen redraw, so hence why it just keeps popping back up). I think it means vram, but it's not super clear, and that probably depends on the particular system and setup anyway.

When you killed QB64PE did you happen to take a look at memory usage? And did you have the A and B programs running?

Thanks for your reply - I did not look at the memory usage, but the a & b programs were not running as far as I could see. If the error pops up again, I'll be sure to check the memory usage. 
Thanks again!
