Re: [OpenMap Users] Openmap 4.6, OS X Java 1.4.2 deadlock

Hi Alexander,

Thanks for the test case, it helped track this down. Turns out, your
example was locking up on the AreaShapeLayer.getMapMouseListener
method, which is synchronized. If you remove that designation from
that method (which now seems unnecessary in the first place), your
example works where it previously locked up. I'm going to make similar
modifications throughout the package.

Thanks again,

Don
