Wild guess: If you are grabbing text from someone to post here, paste it into notepad on a pc (or Mac equivalent text editor with no formatting). Then select it and recopy to the clipboard. Then paste it here.
Great Idea, i may just put all my info and material in to word and format it all to one size, post a few in to a thread and get the correct font size.
Maybe even do my posts in this manner and cut and paste into threads as well, rather than use the Talk Bass editor, cheers for the idea.
