I have recently upgraded a Windows application from version 3 to 8.1.
After replacing the UltraWinToolbars component with the new version I get problems to close an open dropdownmenu. I have to click on the same menu-item that opened the dropdownmenu to get it closed. Clicking anywhere else in the application window will not close the dropdownmenu. Clicking on another menu-item opens that dropdownmenu but leaves it open until clicking on the same item that opended it.
How can I avoid this behaviour?

A managed window is an instance of a .NET System.Windows.Forms.Form, or an instance of a class which is derived from System.Windows.Forms.Form. An unmanaged window is some other window not derived from Form, such as a VB6 window. It sounds like you may be experiencing a bug in the toolbars manager. I would recommend submitting the issue to the support group.
Thanks for your fast response. I have tried to put in the ForceNativeMessageFilter-line on several places in my code but it does not help. What do you mean by "unmanaged window"?

Is the toolbars manager being used in a unmanaged window? If so, call Infragistics.Win.Utilities.ForceNativeMessageFilter() before showing the window (the method must be called at least once per thread a toolbars manager is created on).
If the toolbars manager is being used on a managed Form, it is probably a bug and I would recommend submitting it to the support group: http://ko.infragistics.com/gethelp.
