i know EPi is designed for IE. I have a weird problem. 

Im debugging a custom made Tag function that is not working properly.

The function has a list with available tags, seleceted tags and an ADD button to bring tags from the first list to the second list. 

In IE the css is a bit broken and when you click the ADD button you are asked if you want to leave the page. If you "leave" it the page reloads and the tag is selected. 

In Chrome it works perfectly. The CSS is not broken and when you click ADD the tag is added without anything about leaving the page. 

Any one with experience on how to solve this?
