Thanks for reply
Nope, the "ctrl C" key seems to work fine, the program freezes when I also use the "cut faces tool", I was wondering if there was a way to fix it, but if you think it’s the graphics card or hard drive there is not much I can do about it.
It’s just it would be handy to have these tools, but I suppose working around this sort of problem Maya is best at as there is always another way,
Thanks for your input as it’s taken me weeks to find an opinion on this
