Something to try. Go to Settings/User Options. Click the Display tab.  At the bottom right un-check the boxes for Automatically adjust column widths...and Left Column fix.

No dice.  I had it unchecked already.  When I check the box, it makes things even worse.

When I click auto adjust columns AND left column fixed, it messes up the widths plus I can't adjust them.

Mine have been doing the same thing.  Any luck getting yours figured out?
