I prefer single click (which is on my non wheel group account). But, do to windows default I usually use Double Click so I am used to it on other peoples computer.
Although I could probably edit the registory so that Single Click registors like a *snap* instead of taking longer then a double click in windows. <Windows single click to open is slower then Double Clicking...
HEY!!! My mom is always asking Single or Double click

And she dosn't remember - Icons Double Click, so maybe I should set her Windows box to Single Click mode hahahahahah.
