Just for information...
I don't really have cause to restart my machine, because I have things running that require it to be up most of the day. So, when I ran MFP the next day, I loaded the matches, and the trigger worked as expected, without me altering any settings. I still find it strange why this trigger which MarkV says was working, did not work for me at the time?
All is fine now, but I really would like to figure out what caused MFP to stop functioning. I can only conclude that it must be something I have running, which uses .NET, I develop and test software using .NET, everything else is just standard, outlook, excel, Firefox....
Mark.
