Hi there. I hope someone can help me out on this before I go nuts. I am writing a program for a color VGA screen, with fancy graphics and mouse support. The only problem I have is that my mouse cursor erases or whitens the underlying graphics (depending on the color) when I move the mouse cursor over my pictures. It seems that it is a problem with the colors somehow (I have done similar things easily on a monochrome screen). When in text mode, the mouse doesn't erase a thing, but then pictures are difficult to draw. One other thing. How does one change the color of the mouse cursor? Thanks in advance Brynjolfur Thorsson binni@ed.ecn.purdue.edu

It occurs whenever you try and draw to the screen while the mouse is visible. If you hide the mouse cursor before drawing anything, then unhide it afterwards, this won't happen. >One other thing. How does one change the color of the mouse cursor? I believe the mouse driver is set to use color 15. If you change the palette, for example SetRGBPallete(15,0,0,0) will change color 15 to black, this will change the mouse to black as well. I don't know if you can tell the mouse driver to use a different color for the mouse. >Thanks in advance > >Brynjolfur Thorsson >binni@ed.ecn.purdue.edu Bill Kirby bkirby@cs.umr.edu
