Thanks for your report.

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

When I'm editing a file (using Notepad++) after I edit and save it a couple of times then do another edit, it gives me an error saying the file doesn't exist anymore, even though it does because I just opened it to edit it...

The internal editor always adds spaces every time you save, that's why I use Notepad++, it doesn't add the spaces. Otherwise, I sometimes get an error message that I can't edit the file and run it as admin, but then it won't even save.
