[regex-coach] hanging

Trying to use regex to determine if my regexp are correct. When I use the shortened version it works fine. The long version hangs. The short version: relatedLayers=>[([^,]+,?)+],y=>1,z=>2 relatedLayers=>[MET1,MET2,MET3,MET4,MET5,],

The long version ^boolean=>[ao][rn]d?,comment=>[^,]+,intraFigure=>[01],layer=>[^,]+,relatedLayers=>[([^,]+,?)+],relatedSpace=>\d+,square=>[01],value=>\d+$

boolean=>and,comment=>comment,intraFigure=>1,layer=>MET1,relatedLayers=>[MET2,MET3,MET4,MET4],relatedSpace=>20,square=>0,value=>50

I'm running v 0.9.0 on a Dell M65 (intel Core Duo )
