Windows client: window management issue when the screen containing the Seafile window becomes unavailable

[stuntsman]

I mostly use my notebook with two external screens, while my notebook (as the third screen) is closed.

However, when the notebook is opened, the third screen becomes available. Once I've moved the Seafile client window to this third screen. Later I've closed the notebook screen again - and after that I couldn't open the Seafile client window.

The Seafile client icon was sitting in the tray, and had highlights on focus/blur events as expected, only the window wasn't available on either of the two remaining screens.

I think Seafile needs some adjustments to be able to restore the window even if the screen where it was placed is unavailable.

When I opened the notebook, I've found the "lost" window, that's how I managed to find out what happened.
