Craig,

Are you using any Treeview/Listview active-x controls? I had a situation where I had sub-classed the listview control and used a FOR-EACH loop to move through the items collection and ran into the same thing (VFP7). I posted it here on the UT back in February, received responses but no resolutions. Then one day in May, I received an e-mail from Jim Saunders (Microsoft) with a link to a new KB article (which I've deleted of course). Three months later - Impressive.

The workaround was simple:

local oCollection
oCollection = oList.ListItems()
for each oItem IN oCollection
   ...
next

Something wierd with the for-each through the collection directly caused a dangling reference. Who knew! Hope this helps - if nothing else, it's soemthing else to chase around for a while.

Regards
