I just dowloaded the add-on LaTeX it! for Thunderbird. I'm a one-hour beginner. Something must be very wrong with me or with LaTeX it!.
Indeed, I wanted to compile, inside Thunderbird, a text containing a lot of simple stuff between dollar symbols (the text contained no TeX mistake, since I could compile it in TeXMaker without any trouble). Compiling the whole text did not work, but if I cut the text in three-lined pieces, adding them piece by piece, and compiling in the meantime, and it worked.
I also noticed that sometimes, compiling twice induces mistakes, or sometimes works again. It looks like closing the new message window resets something, somehow, but I don't understand what.
It is hard to provide you with examples of failing code, because when I cut the failing code into pieces to identify the mistakes, it suddenly works. Or sometimes, everything is erased after I press the LaTeX it! button.
Am I missing a general thing ? Are there specific ways to use LaTeX it! ? Thanks a lot !
