Trouble with Fonts in typing Descriptions

I am having problems with fonts at times, and am told it is on my end??? Not so sure of that since I type directly into auctiva and rarely cut and paste.

Also having some mysterious code show in some that do not show when listing is open and previewed but when I close and re-check it is in there.. again, am told it is my issue.

So not really sure.. .

I constantly have problems with the font. IE or Firefox, doesn't matter. Both browsers have different glitches, so dammed if u do or don't. FF makes fonts HUGE!!! but you won't see the hugeness in your preview page, only when your item gets to eBay it's HUGE. Then you have to change it there. I have 30-50 different gripes about glitches in Auctiva's html editor, but my time is too precious to sit here and name it all because nothing will be done about it anyway. Their programmers need to get the BUGS out or re-write the program. I could make double the money I make if the glitches didn't DOUBLE eat my time.
