I have not seen this with IE 11 or Firefox or Chrome. Looks like IE 9 issue. Check if it works from other machine. Also try removing add ons.
You must be correct that it is a browser specific issue. I did work correctly in the latest versions of Chrome and Firefox on Win7. I'd pursue trying other settings in IE 9 to fix it but would rather not since the issue is just an annoyance and using the workaround of another browser is fine.
