Control '' has no parent window - Vcl::Forms::ValidParentForm

I was searching through a text file for the word "summary" and when I closed the search window this error occurred.

WinSCP 5.7.4

Error message:
Control '' has no parent window

Stack trace:
(001D3B5E) Vcl::Forms::ValidParentForm

The problem happens rarely. I cannot reproduce it.

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.
