Today I had training in the morning for a new computer system that is supposed to come in and make all of our lives at work easier.  It will replace the 3 we currently have fun trying to get to "talk" to each other with just one.  Or it will now be a four way conversation.
I sat down at a computer and as usual it was all flickery so I went to change the refresh rate. 
"Stop that, leave that!" a voice bellowed behind me.  "Leave my settings alone."
"But it flickers and hurts my eyes" I whimpered.
The trainer then proceeded to tell everyone that nobody was to touch his settings "no changing the sizes or the fonts". 
Bah!
He then turned the lights off so that we could watch the projector and then all I could see were bright flickering screens mocking me and threatening to give me a headache. 
Every single computer in my workplace is the same.  I think I am one of only 3 people that would know about the refresh rate.  Everyone else just takes Panadol and has a lie down.
