I wasn't able to duplicate that particular bug anyhow... so it is good 
that it is not happening for you anymore :)

Hmm... that is because I need to release ownership of the X11 selections 
(if the clipboard client currently owns the selections) the first time 
that some unsupported format is copied to the Win32 clipboard.  That way 
no X Client will request the clipboard contents from us when the Win32 
clipboard does not contain text.

I missed that one when I decided what fixes need to be made.  I guess I 
will have to fix this now too :)  It will be tough to get it right 
though, because the current code has a lot of special values used to 
make sure that two functions don't get in an infinite loop of disowning 
and re-owning selections and the clipboard.  I have to be very careful 
to make sure that any side-effects from further changes do not cause 
infinite loops.

Nope, what you describe is different than what I said not to complain 
about.  What was happening here is that I called OpenClipboard, then 
checked IsClipboardFormatAvailable and aborted without calling 
CloseClipboard if the desired format was not available.  That left the 
Win32 clipboard locked and prevented other apps from changing it.  Our 
app could call OpenClipboard though, so that is why selecting something 
in X11 fixed the problem.  This problem should not happen when the above 
fix is implemented, but I think it is really worth fixing this right now 
since it is so simple and will prevent really bad behavior.  So, I am 
posting 4.3.0-36 right now.
