>I use vfp3. Is there a limit to how many items a multiselect listbox can have, and reliably keep track of the selections?
Bret,

In VFP 3 there is a bug with multiselect listboxes that prevents selecting more than 60 or so items. It would be much better, in VFP 3 to use a mover dialog type interface with two lists, one of available items and the other the selected items.

As for the maximum number of items a list may have, I don't know of a limit. In my interfaces, if a list will contain more than 1 or 2 hundred items I start looking for a different way to present the stuff to the user. I find lists with 1,000's f item to be totally impossible to use, from the users point of view. Scrolling through 1,000's of item in a list is not my idea of a good way to spend my time so I don't ask my users to do that either.
