Hope you can use my info - keep up the good job guys!

My internet connectivity drops in and out a fair bit; usually winSCP recovers and recognises that any files in my external editor (Notepad++) are part of the reconnected session. The file that caused this error (I was able to edit and save other files) has been in memory for a full working day during which time the session has had to reconnect several times

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

@unclsam: Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
