some of our project administrators have problem to add existing JIRA users to their projects after we upgrade to jira5.1.8 (See screenshot attached). the issue is that the list of available users fragment of the page never seems to finish loading.The "Loading" icon continually animates and nothing else ever loads into the rest of the page, the browser we used is IE. Changing browser to Chrome do fix the problem, but as IE is the standard browser in our company, anyone knows if there is a solution for IE? Thanks
