You said something about “right-clicking” to bring up the menu for {subdividing}.
Two things:
I’ve been using “right clicking” to select (blame Jonathan Williamson for that one lol), so I tried left-clicking, {ALT}, {CTRL}, or {SHIFT} clicking – still no menu. So for sh**s and giggles I tries “W” – voila the fated menu.
I am using 4.4.3 if that makes difference.
