This sounds like an issue that occured with the UltraToolbarsManager, specifically when using a FormDisplayStyle of RoundedSizable/RoundedFixed. I'm almost certain that this was fixed in a hotfix a while ago, so you should ensure that you have installed the latest hotfix for 7.2; you can find a list of the available hotfixes here.

Hi,
I have the same problem using Infragistics 8.1 - it is something to do with using the ribbon, and as you mentione, the rounded corners it puts to give the office 2007 look.
Can anyone help me with this, I have clients on my back because of it!
Philip.
