When you open the video configuration dialog and update the options, click "save" and the popup box is behind the main video configuration dialog box and you have to manually drag it out to click ok.
I think the video configuration dialog box should be push behind the popup box.
Also, the newly selected options including ucode is good for the session only and tr64_ogl.ini is not updated and it is back to default when emu is restarted. below is the default setting that never get changed.

One more thing, do we really have to select the correct ucode for the games we want to play?
It is so hard for gamers to know which ucode to use for which game albeit the more common ones.
