Re: Not responding when try to download file from remote server to local

@shellyleong: So please upgrade. You are not using the latest version of WinSCP.

Not responding when try to download file from remote server to local

I'm currently using WinSCP version, recently I'm hitting the issue upon downloading the file, it keeps show me not responding. Can please send me the debug WinSCP version? thanks.

Hi @martin,

you rock – the development version you created does not have the issue! I cross checked with the latest version 5.19.5 (Build 11933 2021-11-25): WinSCP gets frozen if I have a CIFS 1.0 shared drive connected (which I know is no longer supported with Win10, but that's another story). The development version works as expected.

Thanks a lot for your support!

There are technical reasons why WinSCP has to start monitoring all drives, when you are dragging files, so it can detect where you drop them too. Though this is needed only if you have opted not to install WinSCP drag&drop shell extension (or when you are using portable version of WinSCP or Microsoft Store installation).

Indeed, that's already a suspect I had in mind but did not manage to reproduce yet.
My guess it's either an issue with a network drive which still uses SMBv1 (which has issues under Win10 because Win10 unfortunately always tries SMBv2 to reconnect) or IPv4/IPv6 issues when connecting/disconnecting from a IPv4 only VPN connection.
Anyway – shouldn't WinSCP behave like Windows Explorer: only access a network drive if you click on it?

The problem might be related to availability of network drives (if you have any). Would this help with reproducing the issue?

Hi Martin,

thanks for providing the debug version. Unfortunately today I was not able to reproduce the issue although it was easy to reproduce last week – even after reboots. I will keep the debug version and once I'm able to reproduce the issue I will report back.

@hi-ko: Thanks for your report.
I have sent you an email with the debug version too.

Hi @martin,

if you need another user to generate debug output: I have a similar issue with the latest version (5.19.5 (Build 11933 2021-11-25): Once I drag & drop files from a specific server WinSCP seems to hang and Antimalware Service Executable shows high load. I need to logout or to reboot to get back a working system: Win10 Prof Version 21H 1 (Build 19043. 1348).

Re: same issue

@northerncoder: 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.

You will find my address (if you log in) in my forum profile.

same issue

I am here because of the same issue. I do want to say, other than this bug I love the app.

Re: WinSCP hangs (not responding) sometimes after drag and drop from remote to local

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.

WinSCP hangs (not responding) sometimes after drag and drop from remote to local


First : thanks a lot for the fantastic work ! I'm using WinSCP for a long time.
Now the bad news : there is a bug that is very embarrassing :
This bug was here in the past but it was fixed. And now, it is here again :

Just connect to a remote SSH server and try to drag and drop a file from remote folder to your local folder : sometimes, everything is fine, but sometines, WinSCP hangs.
When it hangs, no arrows appears when the pointer arrives on the destination screen area (local explorer)

Now the versions :
OS Windows 10 Enterprise 20H2
WinSCP : 5.17.10, Build 11087
Protocol : SCP (same trouble with SFTP)
Report log file is attached

I hope you will fix this.
