God I feel your pain D=
I so know how that goes. I'm a computer tech and that BS happens to me all the time. 90% of the work I do is building and/or setting up computers with latest updates so I'm constently having to click buttons. And more than frequently I seem to miss what I want to click on, or click on an ajcent selection in a list. Sometimes things work out for me sometimes not. Sometimes I even get lucky and outwit this unfortunate annomally (Blame it on hand eye or the mouse itself, who cares) and I manage to click on what I want when I think I clicked on something I didn't want.
However I do play arround with art programs (Mostly MS paint or a slipshod wannibe of photoshop called photostudio), Can't seem to draw a straight line for the life of me using a laser mouse. Could do it easy as a cake walk with a ball mouse. Those laser mice have a mind of their own. D= Not to mention those extra buttons tend to be uber sensitive (Mine has a back forward on the sides) which if clicked can screw up something I'm doing... like writing a blog on myspace for example... click it by mistake... might as well go kill myself cause everythnig I just typed vanishes.
