I have several clients complaining that it takes upwards of 30 seconds for a checkbox within IE to display as checked, after they have clicked on it.
I know the browser handles the appearance of the checkbox and radio buttons when they are clicked on, so I was wondering if there maybe an "unknown" issue with IE on Windows XP with Service Pack 2 installed.

My clients are complaining that it happens with both checkboxes and radio buttons. I have experienced it as well. I click on the checkbox and it grays out, then finally it will display as checked.

Anyone else experiencing this or similar issues?
