Thanks Brad.
Apparently I'm the only one this happens to!
I'm over it now and I'm back to my typical zen state (didn't take me long thankfully).
I think my ergonomically cushioned mouse pad is too small for my lumbering hands, but it is very comfy...
Ahhhhhhh!
I was a rook up at the time and my opponent was threatening a queen supported mate and at the same time attacking my queen. Easily refuted of course, I simply chose to trade queens, but to my dismay I landed my queen on the square next to my opponent's queen, giving him/her the choice of grabbing my hung queen or mating me... naturally wasting no time he/she chose the later.
Ahhhhhhhhhhhh!!! F@#$%&%#$@!!
I have to get this out... does this happen to anyone else?
A genuine blunder I can swallow but my sloppy mouse work has got me in a pooper!
