Intermittent problem with Telerik RadUpload File Attachment control in I.E.
Our installation: Gemini 3.1.1
We have found that on some workstations, the "Select" buttons for file attachment (Attachments tab) do not always work when using I.E. Clicking the buttons does not always fire the event to bring up the file selection dialog.
I have been able to recreate this problem on multiple machines. On some, such as a Vista 64 bit, IE 7, the problem happens perhaps only 10% of the time. That is no big deal -- just click again. On others, however, the selection dialog fails to launch 90% of the time. That is very frustrating. That machine has XP, SP2 and I.E. 6.0. The problem is made worse when there are "focus" changes. For example, click on the checkbox, then Select -- it is much less likely to work.
I found this posting on the Telerik website that sounds like it is related:
http://www.telerik.com/community/forums/aspnet/upload/r-a-d-upload-problem-in-ie.aspx
So, is the EnableFileInputSkinning for the ReadUpload control set to true? If so, where/how can this be changed?
Any other suggestion how I can eliminate this problem?
(BTW, Firefox does not appear to have this issue, but that is not an option for all of our users. Also the single file attachment option on the Description page always works.)
