it fails in some form or another in all browsers. tested in IE9, IE8, Firefox 3.x, 6.x, and Chrome. all throw jquery errors when in edit mode on Dotnetnuke PE.
I did do some additional digging and it does NOT occure on the Community edition. I can replicate the problem by following these steps.
1. download and install DNN PE 6.02 trial (also fails on 6.01PE ) just a plain old default install.
2. upload module and put it on a page by itself
3. run the wizard and use just the preselected fields (name email password etc.).
Now try to hit the manage button (which is disabled along with everything else now because of the errors) and watch the jquery errors roll in.
