Winscp keeps crashing after computer idle.

Winscp keeps crashing after I leave my computer. This happens (I assume) once the computer goes to sleep. Also, I'm in a unique situation because I am running Winscp on my Mac (via Wine), and before it worked well (no crashes), but after I updated both Wine and Winscp, it crashes now.

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.

Do you want me to upload the whole file (it's around 400 mb)...?

Please follow the instructions:

Compress the log and email it back to me.
