Hi,

I am trying to display a RadTreeView (build 2008.3.1314.20) in a modal window in Google Chrome (build 2.0.172.33), but the treeview doesn't appear to load. Sample code below (code tested and working in IE7/8, FF3, Safari 4):

Hello Andy,

I confirm that window.showModalDialog does not work in Chrome 2.0. I tried opening http://www.google.com with the same results - the window shows "waiting for www.google.com" forever. It appears that other users have encountered this problem as well. Here is a forum thread discussing the same issue.
