Same buggy results here; using IE9 and Win7 x64. Did experiment with IE9 32bit and IE9 x64, on windows 7 X64 home premie (all running with the usual plug-ins).
There were no issues with IE8, IE7, Firefox 4.01 and Opera 11.11, using the same window 7 X64 platform..
Have not updated to FF 5 yet :?

This post was initial experiment to verify "BUG"... See NEXT post for work-around
