If the rule states an infinitive follows the verb "want", why is "I don't want you worrying" correct?

Solution 1:

"I don't want you worrying about the oral interview."

That sentence is fine. Huddleston & Pullum (The Cambridge Grammar of the English Language, 2002.12311-2) note that "the gerund-participial with want generally has a progressive interpretation, but in non-affirmative contexts it can be non-progressive". They say that I want them standing when the Minister enters is equivalent to I want them to be standing when the Minister enters, contrasting with non-progressive I want them to stand when the Minister enters. However, in I don't want you bringing your dog with you, the meaning is to bring, not to be bringing.
