I have just opened my demo spreadsheet and found that I have lost half of my conditional formatting and graphs that were blue are now green. Yuck. I cant imagine why this would have happened and it is too late to investigate – I suspect changes to the default formats.
Oh well thats what you get for using beta software!
EDIT: WTF The chart formatting seems totally screwed – Now the graph format selections look terrible- live preview seems bust maybe its just me but so far things seem to be going backwards FAST!
