This one drives me crazy. If anyone can shed light on the usage of conjunctive adverbs it would be appreciated. Spell check programs are quick to point out that you need a semi-colon prior to and a comma after the word 'however' (between two independent clauses that is) to avoid a fragment or comma splice. However (no pun intended), after the word 'therefore' I rarely see the comma even though it's presented in the exact same way. I have seen this in many types of scholarly writings and must assume that there is a special rule with 'however' that does not apply to other conjunctive adverbs.
Thanks much for any help.
You're referring to a grammar checker. You can turn this off and just use the spell checker. Computer grammar checkers are nowhere near good enough yet for general use.

However, in a sentence like this, it is necessary. Therefore, there are different contexts in which these words appear.
