I found a solution. It requires opening the Properties for Poser 11, then the Compatibility menu, then click the option for changing the high DPI settings, then overriding DPI options to allow the System (Enhanced) to set the DPI. Apparently, with high resolution displays, scaling the program is hard (I don't understand much of the gobbly-gook descriptions of this on the Internet), but this worked for me. It also fixed the problem of teeny-tiny menus and I could change the user interface back to 1 rather than 2.50 to read the menu items.

This is the menu you're looking for ...
