NetBeans has a word wrap feature now - but if the font changes width when bold then it gets all jumpy and sometimes hard to work with.

Edit: It turns out that even with Courier New that NetBeans word wrap still jumps up and down lines at a time at random. I guess that this question no longer cares for an answer. However,, it seems that there is no answer. (at least nobody has brought one up yet)

I am currently using Comic Sans MS which gets wider when bold.
