"Distorted" was the word I needed! I was sure someone had this issue before but I couldn't find it.
I was trying things like RadWindow looks funny, RadWindow CSS, RadWindow altered, RadWindow bad CSS, RadWindow looks off, RadWindow wrong, RadWindow incorrect, RadWindow skewed, RadWindow displays wrong. Just want to get those keywords in this thread to help others searching for this.
I'm guessing it has to do with our CSS Reset. At least I really hope so because fixing it should be a snap. I'll give RadWindow a style branch for table, tr, td and etc. prior to the reset. Plus this is an old project and CSS is about 40 miles long.
