I try to upload a specific file of approx. 700mb (largest file I've tried to upload thus far). It fails about halfway through uploading with this error and then anything else I do (i.e. directory browsing, etc.) gives me this error until I completely close the application and open it again from fresh.

Thanks for your report. What transfer mode were you trying to use? Text or Binary?

Thanks for your report. I was not able to reproduce the bug.

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.

I plead guilty, I opened a new tab's session in winscp portable, waited for it to have loaded, alt-tabbed to acdsee, selected two jpegs, and drag-and-dropped them, with my mouse and another alt-tab, into the remote files directories display of winscp. That was evil :D

That bug happens from times to times, I can't find a pattern causing it, I can't replicate it.
Reporting it again just in case it may help, that's not a big issue, once or twice a week.
Cheers !
