Concurrent Scripted Sessions

Is it possible to increase the number of concurrent sessions WINSCP can support when running scripted sessions using winscp.com? Each session talks to a different server.

I get the error message "Cannot find unique name for event object" when I try and run more than 5 at once.

I know I'm abusing the product, but the application has to run over a slow (56Kbps) cellular wireless network, so running sessions in parallel is the only way to get a download to all servers in a reasonable time.

That's strange. I was able to run about thirty instances without getting any error.
Anyway I'll try some improvements and will sent you new version.
