@namsic: 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.

When multiple tabs were open, I clicked the mouse wheel several times to close all the tabs. However, there seemed to be some lag each time a tab closed, possibly due to slow server response. It seems that this situation, combined with the action of closing tabs in rapid succession, caused an index-out error.

I had exited from a remote site - I think I clicked the 'x' in the site tab.
Before connecting, I had changed the remote host name.

@marco.benfatto: 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.

I had a bunch of open SFTP connections and i went to quickly close them by pointing on the tab of the first connections on the left and quickly firing the mouse's wheel click to close all of them.

Nobody got injured, but WinSCP crashed :)
Great product by the way, keep up the good work!

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)
Steps I took, just before the error occurred:
I logged into our app server, and system automatically took me to last directory I had been in previously.
I clicked on the right (server) pane header to change the path.
Path navigation dialog popped up, as it has in the past, with current folder path (/misc/.../.../) highlighted.
I was planning to type in the path I wanted to change to /opt/.../... and hit enter, although I cannot remember if I got to type in the full path (just 3 levels) and hit enter, or if it happened when I started to type the path.
That's when the error occurred. I have never seen this error before. />

@jmbier: 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.

I have a bunch of subdomains I can access via
/home/apekholdings/pps.apekholdings.com
/home/apekholdings/???.apekholdings.com
etc

When I try to quickly switch between the directories from the bookmarks window by replacing the ??? with the 3 letters, the app hangs. Basically I'm trying to hop 7 layers deep in the hierarchy without navigating the tree every time and then it crashes like this.

I left the WinScp window idle for 30' minutes in an open session to grab something to eat. Then, when I returned to my PC and tried to open a new sesion in a new tab, this error printed on my screen.

@7kipgod: 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.

What I did to get this error: I connected the computer not through the native LAN connector, but through the USB TO ETHERNET adapter. This is my first attempt, so I don't know what is causing the error. I learned the ip address from the list of connected devices to the router. If you do not use an adapter, then trying to connect to the second PC is not a problem.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
I just clicked on a saved login. There were no other sessions opened. I had already opened and closed multiple other saved logins before I got this error.
Note that it did not stop the connection and everything appeared to work after connecting.
I did not see the issue when I tried other saved logins after that.
The only other thing that might be associated with this error is that I was connecting to the same login with putty at the same time.

@jtz123: 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.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>

Select an item in the directory tree then start typing.
Easily reproduce able and happens often.
Also sometimes get error: External exception EEFFACE

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

I was trying to change the directory, and connection was lost.
If the folder does not exist also, it should throw error, but lost connection and I had to reconnect.

I had downloaded a bunch of files. I used the top menu "Session" --> "Close Session". That caused the "Login" pop-up window to appear. I then clicked on the "Close" button on the "Login" pop-up window. At that point I got the List index out of bounds (-1) message. I tried to get it to do it again, but it didn't happen.
