Winscp not responding after running overnight

How to reproduce:

1. Start winscp (4.2.6 build 721)
2. leave it running overnight (or all day)
3. It stops responding after some time.
4. The only way to end it is to kill it.

I have the same issue.

I have updated Winscp today and will see if it works better tonight.

the upgrade dosen't fixe the issue :(

are some one have a solution or know the root reason of this ?

Regards

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
