Since I have upgraded to Parallels 4.0 I can no longer submit forms on .aspx pages in any browser (IE6, IE7, FF3, Chrome) - the page simply hangs. I know these sites are working as other people on Windows and older Parallels installations are running them with no problems. Does anyone have any ideas what might be wrong? I have just installed a clean copy of XP on a new Virtual Machine and the problem still persists, I'm stumped at the moment.
