Problem with widgets

Hello!

I’m using WordPress 2.5.1. (so far this release really stinks to be honest, so many bugs :O) and I have problems with widgets at the moment. I added few widgets on my 1 and 2 sidebars and when I try to move them away (and save that changes), they still remain where they are – nothing changes at all.
Is it another bug and what I need to do?

p.s. I also have various problems with few plugins, like Polls,etc. which aren’t running good with this new wordpress version.
