EIP popup issue with IE

[bergsj]

Hi,

I have a painful problem with EIP popups on a browse.

My app has a browse with questions. These questions need to be answered using the answer-table lookup (popup).
When in Chrome of FF I can constantly answer questions. (clicking every lookup button on every row in the browse).
When in IE7/8 I can do that for a couple of times and suddenly nothing works. That means the last lookup on the screen freezes (I cannot click on the rows anymore). When I close the popup using the close button, I can open a new lookup, but still I cannot click on a row in that browse.
The only thing solving this is going all the way back opening the questions browse again, so basically start over.
IE is also reporting lots of javascript errors. See below.

Code: [Select]

Anyone have any idea what this could be?
