pca OLE file transfer hangs

[yongbum]

Hi, I have pca 10.5, my customers have pca 11.
The pca 10.5 is the host. The pca 11 remote runs a vb app.
using pca OLE routines.
My problem is the 1st file transfere (from remote to host) sometimes it works sometimes it just hangs (file transfer waiting).
Any ideas how I can kick start the 1st file transfer. Once that works the rest works OK.

Thanks
