GNUstep or X11 Problem

[Andreas Höschler]

Hello all,

I have discovered a serious problem on our GNUstep desktop and am not 
sure - actually I have absolutely no idea - whether this is a bug in 
GNUstep back or a general problem of X11.

I start two GNUstep applications. In the first app I click on a button 
knowing that the operation behind the button takes approximately 10s to 
complete (some kind of complex export). During these 10s I can do 
absolutely nothing on my desktop. Under MacOS X I am used to simply 
activate another application in the meantime e.g. Mail.app or do some 
stuff in a terminal session. I of course can do nothing in application 
A as long as its main thread is performing some operation. But on 
MacOSX I can simply activate another app by clicking on its window and 
stay productive. Not so on my GNUstep desktop. I tried that with Window 
Maker, Enlightenment and GNOME and got the same problem with all three 
window managers. :-(

I suppose, this is a general issue of X11. Can anybody with more 
insight confirm this? Or is this a problem in GNustep back?

Thanks,

   Andreas
