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.

Hi John,
You can attach a file to your post by going to the Options tab when posting. So you could attach a video that way (assuming it's small enough; there is a file size limit). You could also post some screen shots that way.
I vaguely recall that there were some bugs when using some of our controls through Citrix and I am sure we made some fixes to our controls to fix some of those issues a few years ago. I don't remember exactly what those issues were, though. And I am pretty sure I've never heard of anything like the boxes you describe.
Do these boxes show up in addition to the dropdown window? Or instead of it?
Is the color of the box the same as the system tooltip color? If so, then it could be that the boxes are tooltips that are simply being improperly positioned or sized. If that's the case, then I suspect the fixes we made will help you, because I am pretty sure they had something to do with detecting the appropriate screen size and coordinates in a Citrix environment.
So my first suggestion would be to you to update to the latest service release. The last service release for v9.2 was 20092.2119, quite a big jump from the 2083 build you are using.
If that doesn't help, you could try upgrading to the latest version of NetAdvantage (2013.1). You could download the trial version and test it out to see if it fixes the issue before you buy, of course.
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.
