Though I am probably misunderstanding these authors' teachings or context, I have found that David Short makes a statement in his book that the locative case is required after 'o' (about). However, Heim's textbook has the example of 'zajimat se o koho co' (accusative). I must be missing something here. Any explanation for the difference. Thanks.

Dekuji Wicker 808. The full article is very enlightening though somewhat daunting, but it explains my question.
Wicker808, Thanks a million for that WIKI address. I really appreciate you giving that to us. Merry Christmas, Dan
No problem, DanielZ. There are some good articles there, but it's highly incomplete and full of small errors.
There are a few other prepositions which can take multiple declensions, depending on context, usage or the verb used with it, e.g. "v" and "na."
Yes, Sova, I have been noticing what you mention, especially the usage of certain cases with certain verbs. At times, it appears that certain verbs require a case, no matter the position or usage of the declining word in question. Some verbs require a case such as rozumet and others require a set preposition in a particular case. Very interesting.
