Selecting text in tab shifts the view & Alt+Tab brings wrong window to front

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.

Can you send me the .glyphs file (with the tab open) that I can try that myself?

And the other issue is out of my hands as the system is responsible for this.

Will send, also selecting with the cursor in the left direction doesn’t cause this issue.
