HELP: Yeast 3-hybrid problem

Hi,

I'm trying to do a yeast 3-hybrid screen using Clontech's pBridge and 
pACT2 vectors. My problem is, that whatever vectors I transform the 
yeast always grows on -His media, even when I transform empty pBridge 
and pACT2 vectors and rise 3-AT to > 200mM. The yeast wt-phenotype is 
OK (tried CG1945 and Y190), I repeated my transformation with a 
complete new set of reagents and media, still the same result.
Has anybody got an idea what's wrong ?
