Strange behavior - please help

I have a very strange problem. About a month ago I got a new Fondriest Max Carb frame. It was great
for the first three weeks. For the last week I've been getting this strange problem. Here is the
description:

If I ride sitting down everything is fine. When I stand up and accelerate for about 10 to 20 sec.
and then sit back down the bike starts drifting to the left, then to the right. It goes back and
forth like that for a while and a minute later it is normal again. I went to the bike shop and a few
people have ridden the bike and the consensus seems to be that it is either the fork of the headset.

Has anyone out these seen something like this? It makes it impossible for me to accelerate when I'm
riding in the pack and also difficult to
climb.

Thanks for your help, Alex.

Or the frameset-i would check the frameset alignment and also try a ride with different wheels...i
would say have the bike shop stand behind it, but according to Fondriest's latest adverts, bike
shops are unneccasy 'bumps' in the buying process...why they went direct...

Drifting to the right then to the left? Hmmm... Check the ratio of dextrose to laevulose in
your diet.
