Previous shotdown was forced by holding power button. Start Windows (cold boot), try to start WinSCP from start menu pin, got this meesage (not sure how long after clicking the pin as I was not paying attention to the computer for a while after). I see a previous issue marked as resolved, but my window was not aligned with top or left monitor edge previously.

Occurs when launching program after install on new laptop. Once I log into a site, I cannot navigate to directories. They are grayed out. My other laptop has 5.17.3 and I don't have an issue. I grabbed that version for my new laptop and I'm up and running on the older version.

Just installed WinSCP on Windows 10 computer. Every time I start it, it shows this error. I tried uninstalling and installing again and the same message.

If I press <ok> it continues, but I when I open a session to a remote computer I can only see the files. I can't select any or change directory.

If i make a clean install of WinSCP (only changing the drive), when I try to launch the program I receive this error. I can run the program but the "connect to" popup isn't showing.

WinSCP 5.17.4

Error message:
Cannot change Visible in OnShow or OnHide

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.
