The issue I'm seeing is actually on an NT4 server with IE6-sp1, but I'm asking here because there aren't enough people following NT4 newsgroups any more, and I figure that NT is similar enough to XP in this situation. The problem is that these graphic symbols or control elements are screwed up: - window minimize, maximize, and close buttons (upper right-hand corner of any window) - scroll bar up and down arrows, arrows for drop-down lists (the actual small black arrow) - radio buttons and check boxes are screwed up and seem to have been replaced with numbers or letters (in the case of the first two items) and radio buttons and check boxes are so mangled that it's hard to tell when a check-box or radio button has been set or is empty. The system in question has been like this for probably the last 7 years, and I have no ides what might have triggered or caused it. What part of an NT / XP system is responsible for rendering those window and menu-interface objects? I've re-applied the last service-pack for NT4 (SP6a) and re-installed IE6-sp1. I've changed the video card in the system (from ATI to Nvidia) and installed the correct video drivers. What API, GDI, kernel, DLL, VXD, activex, directx, or font files (etc) plays a role in rendering these particular window control elements or objects?
