Description

When I add a CMFCRibbonComboBox control in the status bar, the popup of the combobox is not correctly displayed if it has more than 7 items AND the app is maximized.

The combobox popup is strangely displayed. Cannot use this control because of this problem. This is a BIG bug, proof there has been no testing AT ALL on this class.

See screen capture and more info in this MSDN thread:

Hello Pierre,

Thanks for the report. We have investigated and this issue has been fixed in MFC for the next major release of Visual Studio.

Hello Pat,

Yes you are right, I was a bit rude on this comment, sorry.

Hello Pierre,

Thanks for the report and for adding the repro project. I can't help but note that your statement that this is "proof there has been no testing AT ALL on this class" is a bit hard to support, given that your scenario involves 1) using the CMFCRibbonComboBox control in the status bar, 2) making sure it has more than 7 items and 3) maximizing the application. This must be a scenario that was not part of testing.

We will investigate this bug and report back here on our findings.

I've added a small solution sample to reproduce the problem. I did not notice that no item should be selected in the combobox to reproduce the problem.
