Problem with OnLButtonUp()

Environment: VC++ 4.2-flat, Win 95

Hi there,

I've created a MDI Application with several Splitter-Panes in the 
CMDIChildWindow. In two Panes I display two modified ListViews:

CListView
      |
      |
CLVExtension
      |
      --- CLVOne
      |
      --- CLVTwo 

Both Lists have the LVS_REPORT - Style supporting Drag'n'Drop.
No Problems here. 
If I add CLVOne::OnLButtonUp() and CLVTwo::OnLButtonUp() using 
Class-Wizzard, both methods are never called. This looks really 
strange to me, because OnLButtonDown() and OnMouseMove() are working fine. 
Observing the Lists (Spy++) I've found that the message WM_LBUTTONUP is 
posted! (I'm not using API functions like SetCapture() )  Any suggestions ?

Thanks for your help

I had a similar problem once. The drag and drop feature uses GetCapture to
work properly and then the WM_LBUTTONUP is captured and you will not get it.
I used the following work around: In OnLButtonDown, if the Drag and Drop
succeeded I reposted the WM_LBUTTONUP message.
May be you have the same problem.
Hope it helps...
