We looked the issue, and wasn't able to reproduce it. We also asked for more information and was never responded to. If more information isn't given, then it's harder to track problems down. People say they have an issue, but don't open a ticket so it can be logged.
If I where to uninstall IP through Impulse all of my application icons would become the standard default icon for Vista. As well as certain file types, dll being one of them. Now if I uninstall IP through SDC only the blank icon bug only occurs with DLL files
IF the IP theme I had previously applied has an icon replacement for that specific file type it becomes the generic blank icon. This also happens to the DLL format if I try to reapply the default icons if the Ip im currently using replaces that filetype.
Im not even venturing into the shell issue that still remains in 64-bit which hasn't gotten the attention I had hoped for.
