Now I have tried ME2.0 on my PC.
Here it's clear how great is their work, it scales beautifully from 640x480 of my carputer to 1280x1024 of my PC!
And it works regardless of international settings (in ME1.7 you had to set USA as country in windows).
Now I see what I was missing on my carputer screen because of overscan. ME says "busy" or "database online", so some suggestions aren't correct.
However you should display these messages in center screen, or implement the "customize window size and position". it shouldn't be difficult since ME2.0 interface is already resizable by screen resolution.
It works FAST on my Athlon XP2500+@2250 mhz. So the responsiveness is hardware-dependent. Maybe some tweak in the refresh DB routine...
Music should continue to play while selecting external applications!
