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.

You will find my address (if you log in) in my forum profile.

This was already fixed. Thanks anyway.

Invalid Access to Memory

Hi,

I'm using WinSCP v3.7.5 (build 294) and I have noticed that this "Invalid access to memory" exception orrucs usually when idling in the server so far that you get kicked out for timeout. The error message jumps out usully before "Reconnect" -dialog.

I have experiment this bug since so far I can remember (> v3 or so) so it is not just in this latest version (v3.7.5).
sasquatch

I have downloaded winscp 3.7.1 stand alone application and I will give it a try and let you know what happens...thanks
martin

Can you try version 3.7.1 or older?

Re: Invalid Access to Memory

What do you do when the error occurs? What version of WinSCP are you using?
sasquatch

Invalid Access to Memory

Winscp keeps crashing randomly and keeps flashing a msg to the screen saying "Invalid Access to Memory" Is there anyway to determine why this error is happening. I have kill winscp and restart
