Drop down menus

Hi, I just recently reinstalled CS3 on a new computer, and I noticed some things are different from the other CS3 I had installed.

The most annoying thing I noticed is when I left click on one of the toolbar icons (e.g Rectangular Marquee Tool) I get a drop down box showing the other Marquee tools, as if I right clicked it.

I just want to be able to left click and select the active tool, not be bugged to choose which tool every time I click a tool with a drop down list..

Can anyone help?

Behaviour cannot have changed if you've merely re-installed CS3.

Quick left click to select the active (currently visible) tool.

Left click and hold for a second to choose another tool from the dropdown menu.
