Thanks for all the help. I did re-download the previous version and am now running that alongside the Beta. I find it annoying I can't seem to remove the beta from the Open With menu as it appears above the 2.3 version. Just a Mac annoyance, that.
To clarify, I did update to the Beta and that UPDATE the icon in my dock to the Beta as well. It was a useful exercise that I now know to avoid in the future. My hubby always says "Being on the cutting edge is good. The bleeding edge? not so much..." so maybe I will opt not to update to a beta till the kinks have been worked out. Cheers all...
