Problem with sidebar widgets after upgrading to 2.7

Hello,

I have this strange problem, when I try to add a widget to the right sidebar, it automaticly adds it to left on. I’m using the widget tool in wordpress and it’s unpossible to add a widget to the right sidebar, everytime I go to right sidebar and hit add.. beside a widget i want to add, it adds it to the left one.. any solutions about this problem anyone..?

Note – I don’t have any widgets added on the left sidebar.

Thanks, Dusan
