Hmm... can be just about anything, esp. with the execution of the other programms. Maybe one of them has the leak. However first thing I would do is update to SP5 (that's better anyway) or upgrade to VFP7 <g>. If that doesn't help. See if You are a good boy and clean up Your room every evening <s>. I mean have a look if there
are any nested object-references that are not nullified before their parents get released. I found VFP6 being
quite generous concerning dangling references. VFP7 seems to be much more *accurate* concerning this and does
send You directly to hell if You do it the wrong way.
