Bug reports without an attached log file are usually useless.
Let us know if it ever happens again.
I don't know why but after a system restart it did not happen again. Thank you for your help.
Re: WinSCP crashes after screen rotation
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.
