I have a very specific problem with the RadComboBox. I am using it in a RadWindow that is opening like a dialog, and it is near the bottom of the window, so that the expanded drop down has to open up. If I have enough items that the vertical scroll bar is used, I can select an item and move on, but if I go back to the ComboBox to change my selection, it locks and freezes the whole browser window.
I am using Q1 controls, IE Version 7.0.6001.18000.
This lockup/freeze does NOT occur in Firefox 3, and operates as expected.
I checked the vertical versus horizontal scroll, wrap versus no wrapping text, and it seems related to the vertical scroll. If I limit the items in the list so that it does not scroll, it does not lockup. I tried the default and the Vista skin with the same results.
This is a show stopper for me.
