It might be how it is only going to mins so the exact time timers only need to be check on the minute mark, rather than 60 times a second, thus lightening background tasks mirc has to do.
DaveC, a few days ago you was talking about someone taking you out for a beer, or them taking you out for a beer. I'm far too tired to search the forums for the thread but you probably remember.
Maybe beer should be taken off the agender and have a little coffee instead. I'm out to go make one.
