Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

No idea what happened, WinSCP was in the background for a few days and eventually just popped up this error. The program continues to function normally as far as I can tell.

WinSCP 5.17.10

Error message:

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
I cannot think of what could cause it. Two WebDAV sessions were open. The only suspicious thing for me could be the listing of folders: more than 16000. But the listing was already loaded and I left the app idle for some time. It behaved stable while I was working with these big folders before that.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

I was trying to reconnect to my AWS ubuntu machine after moving my laptop from one internet connection to another. This usually works smoothly and in fact did so this time too. So really, I didn't experience any problem - I just got the error message.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

I left WinSCP running for a few days, RDPed in, used the computer for a while, then found WinSCP while Alt-Tabbing through my Windows. I have two tabs open, not including New Session. I have a workaround (restart WinSCP) so I'm only reporting because the software asked me to.

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.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

This has only happened once and I expect it to be a fairly uncommon corner case.
I have not attempted to reproduce the problem. Session logging is not configured.
Not entirely sure when in the steps the error happened.
1. WinSCP left connected to a site within a corporate VPN.
2. Computer goes to sleep for several hours.
3. On wake the computer is disconnected from the corporate VPN.
4. Computer is reconnected to corporate VPN.
4. When accessing the open WinSCP window, the error message is displayed.

Hope this helps!

Unzulässiger Zugriff auf einen Speicherbereich - Vcl::Comctrls::TTreeNode::GetTreeView

Hi,
the error happened when the program window was open in the background in a remote desktop session.
Unfortunately I did not notice when it exactly happened. When I took the application window in the foreground again I saw the error mmessage.
Kind regards
Detlev

Precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.

Downloaded some files, and then idled for a long time (2-4 hours). This is the most I could remember.

Here is the error:
I leave WinSCP running connected to one or more servers when I shut my laptop. Currently there were two servers connected. Last night, I was using my computer as a laptop, which has different screen dimensions than my desktop monitor. This morning when I woke the computer with it connected to the monitor, the error occurred. I don't think I even clicked on the app. Other than that, nothing unusual.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

App was idle for 4-6 hours following 500GB+ background transfer. Left it in background and it crashed after about 15 min of surfing the web in Firefox. The only other activity before the crash was opening a single This PC explorer window to check HD capacities.

Invalid access to memory - Vcl::Comctrls::TTreeNode::GetTreeView

I had left WinSCP open in the background for a few days while connected to an SSH target, and when I came back this had occurred. Sorry I don't know more.

Invalid access to memory location - Vcl::Comctrls::TTreeNode::GetTreeView

We noticed different behavior of WinSCP.
- WinSCP is halting after some days of running in the background. At some time WinSCP does not respond to any input. Window becomes grey. There is no error message available.
- Sometimes an exception is triggered, see below stack trace. WinSCP still can be used after this message.
WinSCP is being used with one active SFTP connection.

WinSCP 5.19.5

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.
