One of our users has been having a bizarre issue in CS5.5 where it duplicates things. Last time it happened it randomly created six copies of everything in the whole file but it doesn't always. It's been known to randomly duplicate, layers, images, both within movie clips and globally. There doesn't seem to be much logic behind where the duplication occurs, except it tends to be after he imports a vector.
He's running Flash 220.127.116.119 on Windows 7 64bit.
Does anybody have any clue what's causing this and what we can do to resolve it because it's really causing some spectacular disruption.
It's definitley not a keyboard issue. I can't seem to identify a pattern, unfortunately. It just seems to randomly spawn huge amounts of duplicates of everything in the whole file. I thought it had calmed itself down but it's just happened again.
There doesn't seem to be any rhyme or reason, resetting preferences doesn't help. I might just upgrade him to CS6 and hope it works. Not an ideal solution, though.
