OpenGL problem on XP, wglMakeCurrent changes tooltips behavior for windows desktop
-
Hi, I need a little help here from the community members, I'll appreciate if you share any information about this problem if you saw it and tried to fix it or actually fixed it. The product I am working on invloves OpenGL APIs, but 1) On Windows XP 2) and on all kinds of Graphics cards we have (Nvidia, Wild Cat) here at the office Windows desktop tooltips get completely garbled after a call to wglMakeCurrent function. As soon as the window whose DC was used in wglMakeCurrent call is destroyed, the tooltips come back. By tooltips getting garbled, I mean that hovering mouse over program buttons in the taskbar would show wrong information for running programs, the tooltip window's size would be either smaller than the size the tooltip's text can fit in, or too much large showing the extra area as shadow or black color. Any hints.. ideas? Yawar
