Bazus,
it would be better if you set up your left column's width as a percentage and not a fixed width. This way it could adapt to your visitor's browser window more easily.
Now, there are two ways to do so. You can either change the td#leftcolumn value from '170px' to something like '20%' or '30%', or you could hardcode it into your theme by doing something like:
<td id="leftcolumn" width="20%"....>
... etc. I hope you get my point. Now, the widths of the usermenu and mainmenu are always in respect to their parent elements, which in this case is the leftcolumn id!
Please note, that if you specify a width in your CSS file, then this will over-ride the value you specified in your theme.html file. So, choose one of those two and avoid using fixed widths
