Hi,
    Not sure that I remember it right but we had a guy here with the same 
problem. I _think_ he said he adjusted the pH and that fixed it. Not being 
familiar with the pGEX system, I don't know whether he raised or lowered it. 
Still, it's somewhere to start. Hope thats of some help,

      Simon.
