Andrew,

I have not seen a freeze like this that is related to *code* but I have seen instances of a freeze when there is a corrupt index that FoxPro is using to do the search on. Is the LOCATE optimizable such that it is using an index? If so, try reindexing. Corrupt indexes seem to be the one area that do not always get caught by the error trapper ie. instead of an error being triggered, the machine just hangs.

If that is not it, how about posting the code and maybe there is something going on that is not obvious to you with your loop construct.
