Hi Karl,

Thank you for showing interest in win32 interface.

I am studying the win32 interface code to see what is the best approach to 
finish the job.
The best approach is I thing to finish it at ‘message’ level one by one.
For example:
Finish LM_CREATE for all components + testing.
Finish LM_DESTROY for all components + testing.
Finish LM_SHOWHIDE for all components + testing.

And not ‘jumping‘ from one bug fix to another bug fix.
With this approach is too difficult to organize the ‘work’.
And there is the possibility of to much method/event that’s not implemented 
with the above ‘jumping‘ approach.

At this moment there are no win32 team group.
You can send E-Mail directly to me for offline ‘work’ discussions.
And team up with me?

I personally think that LCL + (GTK/Win32) interface should have the same 
behaviour as VCL and/or CLX.
This is to avoid long discussions.
If the GTK interface is not VCL/CLX compatible then the GTK team should fix 
it if possible.
