I have searched the forums and tried a couple of the things that I found there, but still can not correct an issue I am having with the radEditor. If I open the image manager, and click the upload tab at the top, then leave it open for awhile (10+ minutes) before browsing for an image to upload, the entire dialog window will timeout when I click the upload button. This does not occur on my local machine, only when I load the app to our production servers. Also, the problem seems to only occur with IE. I've tried the window.setTimeout function to manually open the dialog window and increase the millisecond count, to no avail, and my version (2008.3) does not support the cookieTimeoutLimit property. Any ideas on how to eliminate this problem?
