In reference to my thread on CodeProject (
http://www.codeproject.com/Messages/4476884/WinXP-problems-after-migration-from-Ribbon-dll-to-.aspx), I attach a sample project (VC++2008) that does not work properly on Windows XP. This simple application has only four buttons: all works fine on Windows 7, but on XP none of them works good:
- ribbonButton1 shows simple MessageBox, which is inactive: I can't even close it:

- ribbonButton2 is a drop-down, which has two items: ribbonButton3 and ribbonButton4. Both have OnClick event that should show simple MessageBox. But it doesn't work.
- Orb menu has one item, which should show another MessageBox, but it does not do.
