Hi Gambit
Thanks for the Post_Message / TIdNotify tip, I will implement this.
I downloaded the snapshot 3 days ago, the date I gave was the actual date
modified date of the idFTP.pas file and not the snapshot, however, I may
have downloaded an old snapshot? How do I know what version I have vs.
current snapshot version?
There does seem to be a problem in Vista, since the post I ran some more
tests from Vista Pro and although it is early days I have noticed the stall
problem only may only be happening when passive mode is NOT set. Here are
some stats for 26 files of 119MB :
Windows XP 45 minutes (passive off)
Windows Vista Pro 90 minutes (passive off - a lot of stall messages caused
by OnWork event not been raised)
Windows Vista Pro 52 minutes (passive on)
Does that make sense?
Regards
Barry
