I'm running a local dev server on Windows 7 with IIS 7.5, .Net 4. Sometimes I get exceptions on one of my sites that don't come out as the normal yellow background red font screen, but as a bunch of symbols that aren't legible. I've never had this happen on any other computer, it's difficult to describe.

Sometimes if I debug it it will catch the exception and I can view the message, but sometimes it won't. Other exceptions produce the standard error screen, this only happens occasionally.
Has anybody else every experienced this? Any ideas? Thanks!
