Problem with Ultimate Zip : it’s not high DPI-aware, or at least not completely.
On my setup (24″ monitor, 1920 x 1200 resolution, Windows 7 Display at 150 %, Use Windows XP-style DPI Scaling = Yes), the ribbon interface is so tiny it’s useless. Fortunately, there’s an option for a classical menu interface which displays correctly, but several dialog boxes have text which is either exceedingly small, or cropped-out horizontally, which severely reduces usability.
Workarounds welcome, if any exist.
