Comment (by joebt):

 Tor browser is again starting w/ part of the browser toolbar and window
 sizing buttons off the monitor.  By default, TBB starts in a partial
 screen mode.  The only way to access the hidden window resizing buttons is
 to grab the bottom edge of browser window & drag it up some.

 Then the top of browser screen automatically "lowers" a bit, where the
 resizing buttons are visible.

 I'm fairly sure this is due to setting my Windows DPI to greater than
 default (96).  For a while, it was set at system default size & there was
 no issue w/ starting TBB UI height.  As soon as I changed the Windows DPI
 to > 96, the TBB opening size was once again too long.
 See orig screen:
 https://trac.torproject.org/projects/tor/attachment/ticket/9268/TBB%203.5%20title%20bar%20sometimes%20hidden.jpg

 I checked a clean install of TBB in new folder (no addons, plugins) -
 still showed the opening screen height problem.

 Note:  TBB is the '''only''' app I use (out of many) that has a problem
 opening the correct size when the system DPI is > 96.  Why is that?
 Vanilla Fx, nor any other prgm have this problem (large corporations or
 one man developed apps).  Is there something inherent about TBB that
 doesn't handle non-standard DPI settings?
