I think some programs hate Object Desktop, cause both Ares and IE7 do it when I use my Mac theme. Use firefox

I know exactly what the original poster is talking about. It's unavoidable with any theme you use through WindowBlinds or another skinning application. You basically have to turn the theme off for IE7 in the WindowBlinds settings, which of course results in the browser having a Windows 98 look. At least, I think doing that worked...

The only other way to have your cake and eat it too is to find yourself a copy of the UXThemes Multi-Patcher utility, which basically hacks the uxthemes.dll or whatever so that it doesn't check if a theme is an authentic Microsoft-authorized one. Then, you just use whatever theme you like, without having to have any software running in the background. Seeing as how this does involve hacking system files, however, it's a risky venture that has given a lot of people little more than grief. As such, WindowBlinds is much safer, not to mention it has all those extra features and whatnot.
