The last rev (3615) built without problems, thanks.
About MacOSX behaviour:
There seems to be no memory guzzling in this version.
However, there is a graphics problem.
If I create a frame and a button, I see nothing in the graphics area.
However, if I open the Properties and change some settings, the layout appears.
But if I click in the graphics area (e.g. to select) or change focus between the windows on the desktop, it becomes white an all contents disappears. Window refresh seems to remove the content or paint it over.
Some "minor" things:
Scrollbars and splitters needs some work.
How do I remove an object? Right-click does not show any context menu of operations as I would expect. Selecting a button and then do Edit/Cut does not make it go away, but it crashes CB.
This is about as far as I have gone for now.
