Yeah, yet another important problem.

Well, this proves that it is not possible to write an application to 
work on all these...

Once, or from the time of that call?

Yeah.

Remove, or set the behaviour it the AES supports now?

If the answers to the last two questions are 'the latter' then I agree 
with you completely Arnaud. Your proposal is better because it does not 
define any new AES API entity (no #define...) and is quite consistent 
with the other usage I must say.

Sure. It is a matter of the AES itself.

Yes, they are already working properly IIRC.

It is not a problem to send the 'desktop redraw', but rather handle the 
redraw action by the desktop application. Now it is different than the 
other window handling which is the thing we are trying to change.
