Hi i'm trying to use BitBlt to compare images, but when i use

BitBlt>>copy: destRectangle from: sourcePt in: srcForm fillColor: hf rule:  
rule

with rule = 32(rgbDiff: sourceWord with: destWord) , it allways returns  
zero...

rule 22 old rgbDiff seems to work just fine...

I'm using 3.8 dev image and a custom windows vm, but i also tried it with  
3.10 and last available vm with the same results..
