All I can say is that I had the application minimized, went back to it with Alt + Tab and then closed a session I had opened (in a tab). I had 2 more connections oponeed. This is something I do all the time, it's the first time i've seen this error. Hope this helps.

The problem happens rarely. I cannot reproduce it.

I was attempting to change my local directory on the "upload" side while closing the session window and reconnecting to the network directory on the "download" side.

Perform steps 3 and 4 almost simultaneously.
1. Wait for session to "time out"
2. Click location profiles
3. Select site location profile and click OK
4. Close timed out session and log back in to it again.

If you are to slow, you will get the alert pop up indicating the session has expired instead of the invalid access to memory error. You have to be quicker than the pop-up to get this error to occur.

I have been unable to reproduce in 3 attempts however.
