On Windows 7 Home Premium 64-bit SP1, I changed the text size to 150% (Control Panel -> Display). This worked fine; all text was scaled up correctly. However, when I tried to change it back to default (100%), not all of the text changed back as expected.
Text within windows, the address bar, editable text in Notepad, etc. are all fine, but window titles, some menus, context menus, and popup boxes (and perhaps others) have really small text, smaller than normal. This is rather annoying.
I've tried switching back and forth a few times, experimenting with the setting. It seems that everything works for any text scale greater than 100%, but whenever I try to set it back to 100%, the aforementioned text becomes smaller. Also, the degree of shrinkage depends on what scale was used last. If I set it to 125% then 100%, the text is slightly smaller (75% size?) but if I set to 150% or 200% then 100%, it is smaller still (50%, maybe?).
This is after changing from 150% to 100%:
Any help on this matter would be appreciated.
