oops, Martin, I'm really sorry for not having answered yet. :(

Unfortunately, in my environment, I may not install a debug version. Perhaps I am lucky and the problem goes away magically. ;)

Stefan

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.

It does. But there is a fair chance that WinSCP crashes and I have to kill it using the task manager (see log excerpt below).
Anyway, it would be nice if one could tell WinSCP in advance something like "this command will take long, just leave it alone and don't bother me with pop ups." ;)

You do not have to click the Abort. You can just wait until the command finishes. The popup should go away on its own.

Hi all,

I really like the execute custom command feature WinSCP offers and use it quite often. An issue occurs, however, when executing a remote command that takes some time (more than a couple of seconds). For instance, when I execute remotely the command
compress "!"
on a large file a message box titled "confirm" pops up after 15 seconds or so. I have no other choice than to click "abort" which disconnects. After that an "error" msg box pops up and WinSCP reconnects automatically to the server if I ignore it. (I once or twice had a bad crash ("access violation ...") at this point when clicking on "Reconnect" but I cannot reproduce this.) Anyway, is it possible to configure WinSCP in a way such that no message boxes appear and WinSCP does not disconnect from the remote server?

When I try running the command in the background, i.e.
compress "!" &
the command is not executed, I get an "error" msg box and WinSCP disconnects from the remote server (and reconnects automatically).

Version is 5.1.4 on Windows 7.

Thanks very much
Stefan
