My first thought is that you should probably consider cutting down on the number of programs you have installed in such a case.
Of course I will make an allowance for there being some extenuating circumstance you left out. So for starters, what resolution is the display running at, and what is the maximum resolution for the display?
on our dell dimension 2350: when i select Start-All Programs--cannot view all programs--the listing is too wide; can't seem to expand, shrink or reposition screen to view them. please advise how to resolve
