in reply to Threads and object access

From what I can make out, the problem is that Win32::OLE in common with many other modules, isn't yet threadsafe. There is some further discussion on this here and some discussion of what steps are required to do it here.

Not a solution I'm afraid, but it may explain some of the problems.

Okay you lot, get your wings on the left, halos on the right. It's one size fits all, and "No!", you can't have a different color.
Pick up your cloud down the end and "Yes" if you get allocated a grey one they are a bit damp under foot, but someone has to get them.
Get used to the wings fast cos its an 8 hour day...unless the Govenor calls for a cyclone or hurricane, in which case 16 hour shifts are mandatory.
Just be grateful that you arrived just as the tornado season finished. Them buggers are real work.
