First off, I don't use the tabbed session feature often. I much prefer a separate window per session (selectable via Win7 task bar).
In versions pre-5.2, opening a pinned or recent session from the jump list will prompt for password and open the session in a new window.
In 5.2 beta, opening a pinned or recent session from the jump list will prompt for password and open the session in an existing WinSCP window. What is even more annoying, however, is that focus does not switch to the window, so if you have an existing WinSCP window behind other windows it will be prompting for a password without any visible indication that user intervention is required (i.e. you have to click to show the existing WinSCP window and then you will see a prompt waiting).
What would be really nice is preference options for:
1) Disabling tabbed sessions entirely
2) Opening new sessions from jump list in new windows
At the very least a reused window needs to be given focus (even for a password prompt), but I also would hope that WinSCP will still cater to those who prefer separate windows. Thanks.
