Comment (by joebt):

 gk, not sure if this has landed in TBB 6.08 final (Win), but it's not
 working (100%) for me in Vista x64 hm. prem.  There are so many bugs on
 "screen size not being reported / rounded correctly," I have no idea where
 to post my latest findings. Sorry if this isn't the best place (let me
 know & I'll move it).

 Suffice to say, if Windows system DPI is NOT default 96, then TBB's height
 is never an increment of 100 or 200.  Never has been, for yrs & yrs.

 As of TBB 6.08, if Windows ** is 96 DPI,** then test sites report 1000 w x
 900 h, on a 4:3 widescreen, 1920 x 1080 monitor.  If the goal is a
 (nearly, not quite) square TBB, it's sort of happening (at 96 DPI).

 If Windows' DPI is say 110, then somehow TBB **still rounds the width** to
 1000, but the height's never a multiple of 100.  Height's always 729 or an
 odd number.  Why can TBB still round the width correctly when Windows' DPI
 is changed, but not the height?

 MANY people older / younger than 60 can't correct vision to 20/20 or have
 problems focusing on the default small font in Windows & all apps, if DPI
 is 96.
 The default font (New Times Roman), 16 size in Firefox -when Windows
 DPI=96 is simply too small for many folks - young & old.

 We can CHANGE the font in TBB/ Firefox, but AFAIK, that will also make you
 different - if sites are checking it - correct?  Zooming a page is
 instantly detectable.

 Thanks.
