[UK-CONTEST] Logging problem

[Chris G3SJJ]

Having calmed down after last night's computer fiasco I am thinking more clearly!

It seems to me that a buffer somewhere is storing the sent information and eventually it gets full. Then when you press Enter it overflows and sends 
the stored info Eventually the keyer goes to a very slow speed, ie about 7 wpm and then stops working.

This time amongst the stuff it decided to send out I heard it send DL4CF which was my QSO number 43. Bearing in mind I had just completed QSO number 
145. Surely info that previous shouldn't be stored??

So is this a function of N1MM or is it something associated with my Vista PC?
