I'm not sure when this happened. I have changed my internet connection between cellular and WiFi couple of times today and at that time my Cisco VPN connection is interupted for a short time too.

No clue what has happened since this winscp session has been behind other windows for a while.

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

2022-02-04 08:23

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.

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

2022-01-01 18:26

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.

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.
