[Openmcl-devel] Can anyone get mouse up events in the Windows/Cocotron version of ccl?

[Gary Byers]

I was going to say that I couldn't reproduce it, but I realized that 
the Cocotron libraries that I was using were a little old.  I updated
my ccl/cocotron directory, rebuilt the IDE, tried your test, and got
the same results that you reported (nothing printed on mouseup.)  That
strongly suggests that there was a change in the Cocotron libraries between
whatever (possibly several months old) version I had installed on that
machine and the versions that we're distributing now.

I can't think of anything in CCL that'd affect this (and certainly can't
think of anything that'd do so intentionally.)

If you still have the application bundle built by XCode, you might try
replacing the AppKit and Foundation .dlls in that bundle with the ones
from ccl/cocotron.  If the ObjC application behaves the same way, then
we can definitely say that CCL isn't involved.

I don't know whether it'd be necessary to upgrade the Cocotron
libraries that we distribute or downgrade them in order to avoid the
problem; Gary Palter may have a better idea of that.

It seems that this is not a cocotron issue because I made a cocotron project that receives both mouse up and mouse down events with no problem using objective c.  The following code illustrates the problem pretty well.  In OSX the  code will display a window and when you click you get both mouse up and mouse down events (as well as drags if you drag), but on the windows/cocotron ide you only get the mouse down and drag events.  Has anyone else experienced this?  Anyone know what is going on here?
