Really I am, sometimes I need to give my head a shake before doing things.
Today I noticed a small black speck moving on my monitor so after confirming that it wasn't part of the web page that I was looking at or that it wasn't a small insect on my screen by trying to flick it off guess what I did next?
Yep, give the screen a little push to see if it's a small insect inside my screen, one small splat later this is now confirmed and I now have black mark which will never come off right in the middle of my eyeline inside my PC screen.
I did crack open the monitor case to see if it was servicable but at least common sense prevailed this time and I gave up after getting the plastic casing off before I did any more damage.
Just thought I'd share that, move along now.
