WHOOPS!   Must just have been some general glitch on my laptop.... Today it works perfectly!  Sorry to have wasted people's time in reading this! :-[
Sorry if this is another of those absolutely basic questions, but I couldn't find anything in the forums about it.
I've just discovered that while I can cut and paste using CTRL-C and CTRL-V within my EB program (into an edit box), I can't do the same from the external programs I've tried  (discovered this trying to copy text from an email).  Wouldn't work with a simple editor either.
Why would this be?  Should it normally occur or have I simply not enabled something in my coding? 
If someone can just point me in the right direction in the manual or in what to look for, I'd be grateful.
