recursion limit when creating file list of harddrive

[Alex Tweedly]

Are you sure you are actually hitting a recursion limit ?

Another (perhaps more likely) problem is that you are hitting a 
protected directory, or one which you cannot access (e.g. because of 
strange character in name).

I would (at a minimum) put in a check that you have moved to the folder:

on directoryWalk whatFolder
   --put whatFolder
   --exit to top
   set the itemDel to "/"
   set the directory to whatFolder
   if the directory <> whatFolder then
      -- give some error somewhere
      exit directoryWalk
   end if
   put the files into temp

If that's not it, then you need to change to a serialized rather than a 
recursive treewalk - I'm sure that's been posted on the use-list some 
time ago (if you can't find it, let me know and I'll dig one up)
