I would really appreaciate, if you follow my previous post a contact me, so I can send you a debug version to help fixing your problem. Otherwise you may end up using outdated version of WinSCP :), as I cannot fix this myself (the error is not hapenning for me). Thanks!

I guess I'll switch back to the latest 4. I'd checked the revision history and saw the "stalled connection auto-reconnect" bug fixed but this raised much more than it fixed. And I found out something else, the stalled connections still not auto-reconnecting. When I got a few Invalid access memory, it keeps downloading, even though the error message window stays there, until you click on it. If you do so, it closes itself. But, it came to a point where the connection was stalled and it gave another Invalid access memory error, this time it didn't keep downloads. So I guess for now, I better keep using 4, since they both cannot auto-reconnect on stalled connections.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

Just upgraded from 4 to 5.0.3 because 4 couldn't reconnect after a stalled connection but it became worst now. I constantly keep getting Invalid access to memory errors (about every couple hours). After 3 consecutive errors it closes itself. Is there a way to get the debug version?
