Please let me know if I'm barking up the wrong tree(thread), but I'm having a problem on my site. It's built on DNN and we use a pop-up window to add comments.  When we bring the cursor over the "Save' button, the window disappears, preventing us from saving the comments.  The site has worked flawlessly for a few years and started running into this problem a few months ago.

It's happened on Chrome, Firefox, and Opera, but on different machines.  It'll work on Chrome on some but not others, same for the additional browsers.  I've trouble finding a pattern.  I assume it's something simple that is just way beyond my understanding.  Does anyone have a suggestion?

I'm assuming there is an update or setting issue that I'm not thinking of.  Any suggestions would be awesome.
