Sounds like you just have a frustratingly slow computer. I can tell I double clicked something by the fact that the thing I just double clicked starts running. Also, it's not like I click too slowly all that often, maybe one time in a thousand, if that.
no the computer and lots in my collection are fire breathing monsters .. i7 3.8g 64bit os, lotsa memory, we are big kids here reallly!
so do you get some indication for all the programs you launch? some are running but take a week of sundays before they spew anything on the screen. there should be some positive indication by the desktop ms os crap to let you know you actually got the motha clicked. even the pdp10 in 1970 said "Ready"
