I wrote a program using VBE 3.0 some years ago and was hoping that DosBox would allow it to run in an XP environment. The good news is that is does run, the bad news is that graphics (that the program draws pixel by pixel) do not render properly. Seems to be a problem setting the palette.

I can get it to run fine by booting to safe mode and selecting "Enable VGA graphics." But if I ever change screen resolution back to 1024x768 or whatever then I'm out of luck.

I would like to run this program without a restart. Please advise.

tried the other svga cards emulated in dosbox ?
although the default is the one with the best vesa support.
If you want to figure out what is wrong. either upload it or take a debugger version of dosbox and see for yourself.

You can try loading a S3 Trio64v+ BIOS with ldgfxrom before loading the hard disk image. I found Windows to be a biiiiiiiiit more stable with a BIOS (despite having a much more limited VBE than the default), and XP should have drivers for the vanilla Trio out of the box.
