I have the following problem with the glN64 0.4.1 graphics plugin with both 1964 and Project64: the "Refresh rate" tab is completely empty! Apparently because of this trying to switch to fullscreen with glN64 causes the emulator to freeze. Also for some reason the "Windowed resolution" tab is empty by default, but at least there I can choose a valid resolution. My graphics card is Geforce 2 MX with the latest drivers.
