Maybe you insulted him telepathically? Your negative energy was soooo strong that it sent him a comment that imprinted on his brain...
Or maybe he's just having a bad day (been there before)
Or maybe its just a love hate relationship (love the software but hate that it doesn't work the way I WANT IT TO)
Or maybe Scott ticked him off with that whole "just kidding" thing (damn you Scott!)
I find that 'unplugging" works well for most of these complaints. Step away from the PC for a bit, have a cold one, go yell at the kids who are stepping on your lawn, find something to do other than staring at the computer monitor and venting.
The Pro version will be done when they're done with it, until then everyone should just CHILL!
Oh and before ya'll start flaming me, I'm JUST KIDDING!
