Context Menu Release

Hi friends,

I have designed an application using VB.Net.
When I right click at the node 2002 popup menu is displayed. Again I right click at another node suppose 2003. There are two different cases

Windows 2000 – In this case popup menu called at 2002 node is automatically released and Popup is again called at 2003 node.

Windows NT – when the application is installed at Windows NT machine popup menu called at 2002 node is not released and no popup menu is displayed at 2003 node. My problem does not stop here. Now when I left click at any node that item is selected but the highlighted node is 2003.





What is the reason and solution for this?


Is there any API through which I can release the shown popup menu at mouse down event then again show the popup menu at the new node?

How this is working properly on Windows 2000 machine?

Note:: attached image shows the screen shot of the problem.
