I have narrowed it down.  The problem seems to be with TLabel.  My component 
consists of a TShape and TLabel sited on a TPanel, which is why I didn't catch it.

Then I thought maybe it had something to do with having the TLabel on the TPanel 
so I placed a TLabel on a form by itself and the problem was replicated.

So it appears that there is a problem with the TLabel and mouse up when the 
cursor is moved off of the label before releasing the mouse button.

I would log this with mantis, but I can never get it to send me my password. 
Yes I have checked my email filters and junk folder ;)

If you care to have it sent to me manually, please email it to
