I run Windows 10 and have the taskbar set to hide when the cursor is not at the bottom of the screen. Unfortunately when I do move the cursor to the bottom edge of the screen the taskbar doesn’t show. This is annoying because if I want e.g. to click on something in the Notification Area I have to minimise OnlyOffice each time.
EDIT: I should have added that it only happens on OnlyOffice.
I.E. On all other applications (including this forum) I move the cursor to the bottom of the screen and the Task Bar shows.
