Thanks Macster; one problem solved! When the cursor didn't change to an arrow I didn't think there was a function there!
Next up, while I'll be gettiing a copy of Office over the weekend and using the email program on there, whose name escapes me, at the moment I'm just using Mac Mail. In OE I was subscribed to several newsgroups; do they exist in the Mac program?
I confess I miss the right click function from XP, and having to go to File - Move to Trash for a folder instead of just clicking Delete. Any other hints feel free to throw them this way.
