Using Build 1966, I was interested in determining the exact maximum windowed screen resolution so I can use the Start bar, etc in the Guest without being in full-screen mode. These are the pixel counts I determined: Mac menu bar height: 22 pixels Window title bar height: 22 pixels Parallels Guest top border trim: 3 pixels Parallels Status bar: 23 pixels Parallels Toolbar: 40 pixels Using these measurements on a 15" MacBook Pro I came up with these custom screen resolutions: Maximum windowed guest with no status or toolbar: 1440 x 853 Maximum windowed guest with status bar (bottom), toolbar right: 1400 x 830 There of course other varations such as toolbar on top, or w-w/o status bar or toolbar but there's enough data here to make those calculations. I hope this helps anyone else looking for this data.
