The first picture shows a signature inserted below my reply, but above the quote. The signature has two extra line breaks (second picture). If the 2 extra line breaks are removed, the signature looks like the 3rd picture.

OK SF, I put two linebreaks (Enter?) below my sig, but there's nowhere I can see to do a Apply, or Save that new sig? I just closed that page and my sig hadn't changed?

Is the sig. entered in Account Settings as in my 2nd picture, or attached as a text or html file? Post a screenshot if you can. Enter might just separate paragraphs, while a space is created with the break tag.

yeah I don't know anything about tags and such, here's what I'm doing.

Add < br > tags to make spaces at the bottom, as in my picture.

That did it, thanks SF!!

Darn, now it's messed up even more. There's now a big space at the top where I can't put the cursor.

The images

It works OK here. The cursor is visible in your picture. Does it work in safe/troubleshoot mode (hold Shift when launching TB)?

yeah for some reason it's working as it should now.
