i navigat on remote host by tipping the start of a directory name and the hit enter to go into it.
it seems like: va<enter>ww<enter>loca<enter>htd<enter>...
now it happens 2 times to me that when i try to hit enter i also hit the delete button. winscp response so fast that it insteandly accepts the enter as confirmation of the delete dialog, and i can look while a whole directory moves finaly to /dev/null
the solution would be easy: just unfocus the OK in the confirmation dialog, or do (like other procs) disable it for about 1 to 2 seconds
PS. i recogniced also that the abort button of the delete process doesnt response on hammering on ESC :? i was to lazy to jump over to the mouse to abort the process xD
