Windows v6 beta test

[ffcmike]

With the latest version I am experiencing a problem when closing the client, as soon as I click X the screen display stays frozen as it is and the client stops responding (though my account remains logged onto the server) until I right click it within my start bar and manually click "close", it only seems to be happening half the time though and entirely randomly, can't really link it to any specific conditions.

I'm also now seeing certain images such as default blue GUI buttons and certain images with a rotation effect (again strangely not all even if they've had transparency configured the same way) with opaque background as opposed to transparent that were previously fine.
