Thanks for your help and thanks for WinSCP!

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.

Thanks for your major donation!

I checked WinSCP.com and It announces itself as:

So WinSCP.com thinks it is the latest version.

The Explorer details tab of WinSCP.com show:


The APPCRASH is still occurring, and still shows:
