They didn't recommend anything specifically--the solution I use is to
make an edit to the file so that the program sees it as "dirty." Skim
has (as do most Mac programs--not sure about non-Mac) a Revert
command under the File menu. Before editing the file, Revert is
inactive ("grayed out") and after the edit it is active--selecting
Revert then loads the contents of the file from the state of it's
last "save."

Here is the most relevant comment from the other group:
In fact PS files are followed for file changes. So the problem is
somewhere else. Probably the PS file is deleted before it is
replaced, in which case it's lost track of.

Not sure, and don't know how to find out. Suggestions accepted.
