Wes actually doesn’t have IE since he only has Mac computers…..so I’ll try and assist.
First, I wouldn’t depend on the IE “Compatibility” mode because it’s definitely not the same as the “real thing”. In my experience it has been very unreliable. So I would recommend testing under the actual browser itself rather than any “emulator” or you will get unrealistic results.
Most developers support IE8 and higher nowadays. Can you tell me which browser version you’re using so I can see if I (have it) and can take a look?
