Upgraded from 11.2.2 (or maybe 12.0.1, not sure) to 12.1.1. In my application I transfer panes the way we discussed here:

http://forum.codejock.com/forum_posts.asp?TID=11590 - http://forum.codejock.com/forum_posts.asp?TID=11590

It worked before, but now I get a crash:

DWORD CCmdTarget::InternalRelease()

{

ASSERT(GetInterfaceMap() != NULL);

...

}

And the reason is that m_pVirtualRow == 0x0000001 at line 79 in XTPReportRows.cpp. I'm not using virtual mode, so I really don't understand how this can happen!

Just to clarify:

I disable/hide a pane in my main frame and attach it to another frame. Changing the owner etc.

Ok, I found the problem. It's probably my own fault, but just to be sure I'll describe what happens.

1) I right-click in one of my panes P (with child window W) and call the blocking function CXTPCommandBars::TrackPopupMenu. The address of some local variables are set using SetTag().

2) I select item X which has a tag.

3) The message is handled in CWinApp, and the tag is used to make some decisions. Then, before P is transfered to another CFrameWnd, a call is made which sets a member variable of W is made. All this call does is setting a boolean member to true.

Setting this member somehow blows the stack. ~CCmdTarget yields a crash (m_pVirtualRow == 0x01). This seems to only happen in Vista! (Memory protection?)

The question is; is this a fault on my side, or could there be a flaw XTP? I track the menu using site=GetTopLevelFrame().

Let me summarize the sequence:

Track popup menu in pane window, handle message and modify pane-member, transfer pane to another pane manager.
