Hi, after reading both your posts, I tried the Desktop mode (in my case it also sets resolution to 640x480) and noticed that, after alt-tabbing, you can click the maximize button on the border of the application, which imo provides a fairly decent resolution while windowed (my screen is 1920x1080 so that's about the resolution I get) :)
There are still some issues with windowed mode, like the fact Enclave window stays on top of all others and that alt-tabbing can make the game crash (happened only once until now, but just so you take into account it can happen), but seems to work well for me.
EDIT : Uhm, didn't comment that before, but I'm using Windows XP.
