Controls vanish after remote sync started in 'new window' and then 'minimized to system tray'

To reproduce:
1. Open 'Keep remote directory up to date' modal
2. After setup, select 'Start in New Window' option.
3. In the status modal, select 'Minimize to System Tray'

The modal vanishes, no tray icon appears and until you close the main window you cannot stop the process, nor restore the window.

Thanks for your report. I'll look at this and I'll contact you in few days.
