[Fwd: Re: emacs w32 menu disapprears after clicking item]

As you can see below I have asked Rainer to try the unpatched version 
and then send in a bug report. I wonder however if there is something 
that can be done in between.

I am trying to understand how it could happen that the menus disappear. 
It seems like the disappear in a certain order, from left to right. That 
makes me wonder if the menu creation functions for dynamic menus are 
protected against errors (and if they can be protected). Anyone who have 
a good grasp of this at the moment?

I have this problem on WIN32 from time to time.  In my case, I  
believe another windows application (In my case, SQLTools,  
www.sqltools.net) is leaking windows GUI resources so the Windows  
system does not have resources available for other applications.  If  
I close that application, Emacs menus will no longer dissapear,  
without any changes to Emacs (don't even have to restart it).

Other applications are also affected by this GUI resource leak: they  
sometimes refuse to display right-click menus or dialog boxes.  It is  
not that nociceable since most applications allocate the GUI  
resources they need at startup.

Kind Regards,
Alex.
