Courses not launching consistently after upgrade from XP to Win7
My team and I are experiencing some very odd behavior after upgrading from Windows XP to Windows 7. If I publish a course in Win7 and upload it to either SharePoint or our LMS it will not launch for me on my machine but will for others on the team whether they are using XP or Win7. If someone else on my team using Win7 publishes the very same SL course it will launch for everyone but them. However if — using the very same SL course — we publish it using XP it launches fine for everyone. This behavior happens to everyone on the team, i.e., if you publish a course using Win7 you won't be able to launch it but everyone else will, if you publish using XP everything is fine.
The XP machines are using IE8 while the Win7 machines are using IE9. In all cases we are publishing the courses from our C drives. (Another thing to note is that on the Win7 machines the preview functions properly for the developer; once you publish and move the file to a server the problems begin.)
Has anyone seen such behavior, and more importantly does anyone know how to fix it?
