Glyphs 1 in 10.8.5
See the screencast for the selecting behaviour

The other issue is that when I have multiple glyphs windows open, If I alt+tab to another program and alt+tab back the Glyphs: another glyphs window is on top the of the active one, i.e. the active one with the cursor/tool is the correct last window open but another one is on top obscuring the active window.
