Gluten Free Bread, Raises then colapses.

Been making a few loaves using dove Farm Brown gluten Free Flour (UK) and there quick yeast.  Have got something edablebut not great.  The problem seems to be the bread rises well but then colapses.  Thinking this may be the quick yeast (if it lives up to its name.  I actualy wormed up the milk I was adding and put the yeast in for 10 mins lat time (have tried bunging everythnig in) but did not see any bubles.

The gluten Free Cucle in the bread maker is 2:55, was thinking of trying 2 houre sycle as I am thinking with the quick yeast it may be that it needs to start cokking a lot faster?  I am figuring if I select the same program and reduce time its the rising time it takes it off, hopefully I am right;)
