Yes the patch was applied. As was also mentioned.. somwhere in that thread,  
the reason it apears to small is because in GTK the Width/Height represent 
the ClientWidth/ClientHeight of the form, so in Win32 it looks wrong.  If 
ClientWidth/Height have been implemented properly in Win32, then in the 
example code changing where it set the width and height to set the client 
width/height should make it apear properly. This is an incompatibility 
between X-Windows and Win32 design, not a problem in the Lazarus code.

IMO there are far too many asserts in the code as is. And they are mostly in 
the Messaging system. If you were too make sense of the ones that were 
there, getting rid of redundant ones etc. this should be enough To begin 
with. then you can start seeing about adding more if it is really needed.

agreed.. but I am going to stay out of this discussion since at the moment I 
won't have much time to commit to the project, so most of my time will be 
spent working out stuff which is on the GTK end.

Feel free.. but as was also mentioned previously, for simplicity sake, start 
all message titles with [Win32]  so that all those who are working in that 
area know too look at it, and everyone else can simply ignore it.
