Hello -
We have a .NET 2.0 Windows Forms application using .NetAdvantage 9.2 controls (9.2.20092.2083) that is accessed via Ericom (similar to Citrix).
We have found that when the application is not Maximized and the user clicks the drop down button on an UltraComboEditor a colored box (color varies depending on the server) is drawn on the users desktop. The size of the box seems to match the size of the window. This is an MDI application and only happens when the MDI child being used is not maximized in the MDI frame.
Depending on where this box is drawn and how large it is, the potential exists for a user to not be able to access anything on their TaskBar. Additionally, if they minimize the application with this box on the screen and it is covering the TaskBar and or Start button it is near impossible to access anything else.
A similar issue occurs with UltraTabControl that have tooltips.
I do have a video that illustrates the issues if there is a way to get it to you.
I have created a empty form (no custom code of any kind) except for a few controls, Infragistics controls and standard .NET Controls. The .NET controls work fine but the Infragistics controls result in the boxes being drawn. I can also provide the example form.
Any suggestions for addressing this are much appreciated.
Thanks.

Sorry, I thought I included the link.
How to get the latest service release - Infragistics Community
I'm afraid that video doesn't tell me much. It's not the same color as the tooltip, so it's probably not a mis-positioned tooltip window like I thought. Perhaps the color is the desktop color and the block is not actually a window that is covering the desktop, but just the opposite - an area where the desktop is failing to paint.
One very interesting thing here is that the desktop image is still there. In know nothing about Ericom, but in my experience with Citrix, they typically do not show the desktop wallpaper on the client machine.
One last question Mike.
Can you tell me how to access the last service release for WinForms 2009.2. I can't find a link on your site to do this.
One of the interesting things about this is that this is only a problem on MDI child windows. Application forms that are not MDI children don't have this issue.
Here's the video in a zipped file, assuming it is small enough in size.
Thanks you for the response Mike.
The boxes show up in addition to the dropdown window.
I have attached an image file as an example. I will try to attached the video in another reply.
Color seems to be the desktop color from the server, though I have not worked to confirm this. As I recall this seems to be the case with the various servers we have had this issue with. The tooltip shows up correctly.
I will download the latest service release and see if that helps.
