hmm ...

anyway i attached a patch, this will slow things down a tiny bit and 
hopefully fix the scaling 2.95.2/.3 prerelease issue
iirc i allready did send a patch a long time ago but noone confirmed if it 
helped or not ...
if it works than it should be added to that unapplied patches section imho
