...there's probably a very simple answer for this ;-)

1.  first off, you should definitely being using a more recent version 
of GEM (I think 0.888rc2 is most current)...this has a huge number of 
fixes, especially to the window handling on 10.3+:  btw, what version 
of osx are you using?

2.  I'm guessing you are using a self compiled version of pure-data?  
If so, this is the bottleneck:  OSX requires certain things to be 
present in an app before it hands over access to the window 
manager...so, atm you can use either the pd++.app at my website (which 
I desperately need to update to 0.37-1), or you can try one of the 
other application bundles that are floating around (I'm thinking 

good luck,
