Missing left hand menus

Hi
WinSCP version 6.5 (Build 16288 2025-03-31)
Windows 10
OS build 19045.5737

I don't have a left hand menu under Options > Preferences
nor under Advanced Site settings.
Any advice?

It seems to be something to do with screen resolution

So can you please share your display setup? Number of displays, they layout, which of them is the primary one, their resolution and scaling.
