I have a webpage that uses sprites for its navigation link. In IE7 sometimes the links are not clickable. It works fine in IE8 and Firefox. Anyone encountered this before?
Thanks.
Edit
To clarify, on my computer, everything works fine. (Vista, IE8, Firefox 3, Chrome, Safari). I had a complaint from some users that the main nav wasn't clickable. Honestly, I thought "user error" and didn't look much further. Last night I saw my wife browsing the site (Vista, IE7), and noticed some times when she hovered over a link it was not clickable. The mouse pointer did not turn into a hand, and the link itself did not turn white. Clicking did nothing. Some links work fine, some are sporadic, some never work.
I've never seen this before, so I decided to ask you guys.
