Hi there -

We just finished upgrading our images from 3.8 to 4.1 and one issue that 
keeps coming up is the inability to resize a SystemWindow other than in 
its corners. I vaguely remember that someone posted a fix for this 
(i.e., so that one can resize windows on any edge) but I can't find it - 
any quick pointers?

Cheers,
   - Andreas
