Sideboxes going gaga

Hello there,

I am now having problems with my sideboxes and wonder if someone has had this problem and knows a fix for it?

The left and right sideboxes are set at 181px and 181px repectively.
From the main menu, everything is okay, but when i go into a category page, the left sidebox expands to nearly twice its width which bunches up the middle section.
It is the same for the contact us page, and compresses the contact form into a rediculously small space!

Any help would be great.

Thanks
Colin

Cheers and thanks for you offer of help.

Colin
