Hi Daz, good advice. I understand I'm not helping the beta process if I don't upgrade. It's just that I was enjoying playing the game using 5.0.09 and when I saw the problems 5.0.10 was having I held back.
I think what I'll do now is go ahead with the 5.0.10 update, play with that (using your suggestions above regarding the Force Data and Edit Task functions) and see what it's like and report any other issues I come across. I believe I saw Dave post in another thread that he was working to get 5.0.11 out this week so it won't be too long to wait.
On a side note, as a new player to the CO family I have to say how impressed I am with what I've seen with CO2 (even with it's beta issues). I'm really looking forward to playing the finalized version.
