On my page, I have a RadUpload control (Q3 2009) which I use to submit images.
After the image has been uploaded (on postback), I hide the upload control and show a "change logo" button. If the user wants to change the image, they'd click on that button and I make the RadUpload control visible once more.
When I do this however, some very strange behavior occurs with the control - its seems like the underlying HTML File Input control is shown whenever the user mouse's over the RadUpload control..
Its hard to explain, so I made a little movie of the issue using Jing: http://screencast.com/t/MDE3ZTA4NG
Is there a known issue with the RadUpload (in IE 8) that causes this behavior on visibility change?
