Reproduced

I've encountered this same error. WinSCP 5.7.6. I had left WinSCP open overnight, I think connected to a server via SFTP. When returning to my PC, I saw the error.

Control 'MainMessage' has no parent window - Vcl::Controls::TControl::GetDeviceContext

I was just sitting and watching browser, doing literally nothing with the app minimized. Then this pop up suddenly flashing asking me to send this. The app wasn't closed for several days, maybe even week(s) (I don't cared about it and just maximized it when needed), the connections were certainly lost during several hybernates.
This is really not a trouble for me, but well, it asked nicely to send this and is really a nice app ;) It is the first time I've encountered it.

I had WinSCP open for several days but the client was no longer connected. Eventually this error message appears while the session was inactive.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
Seems to be related to a WinSCP window being left open, though this is the first time I've seen this Error, so it definitely happens rarely.
The window was connected to a Google cloud Linux instance which was unintentionally left open for ~48hrs.

Control 'MainMessage' has no parent window - Vcl::Controls::TControl::GetDeviceContext

Left it running over a four day weekend, unlocked my computer and was presented with the dialog that brought me here when I clicked 'Report'. I have no idea what would specifically trigger the issue. I do recall being connected to four different SFTP sessions where two of those servers frequently disconnect me - if one of those tabs is selected, WinSCP will generally try to reconnect. Perhaps there is something funky when a desktop is locked and a server disconnects.

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.

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.

Control 'MainMessage' has no parent window - Vcl::Controls::TControl::GetDeviceContext

Left WinSCP ruuning over a weekend with approx. 4-5 open connections.

Logged in Monday morning and found this stack trace on the desktop.

btw. apparently the Win7 host that WinSCP was running on got disconnected from the network during the weekend.

I left my computer for the night then came back and it had this message. Looks like it was trying to reconnect to a host when this happened.

Control 'MainMessage' has no parent window - Vcl::Controls::TControl::GetDeviceContext

connect to host using winscp. Disconnect network forcing winscp to try to reconnect. allow to "fester" until it confuses itself and this error happens. (likely a race condition between windows.

The parameter is incorrect - Vcl::Controls::TControl::GetDeviceContext

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>

Not sure what happened, just came back to my computer after a while, to this error message (asking me to send report, here it is )

Control 'MainMessage' has no parent window - Vcl::Controls::TControl::GetDeviceContext

I had connected to a remote SFTP host and was transferring a file. The connection was lost (server-side issues) and I was waiting for the connection to come back up. I left the application running overnight; I am unsure how long after the connection was lost that this error occurred.
