Status: RESOLVED WORKSFORME

(Thunderbird :: Untriaged, defect)

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:17.0) Gecko/17.0 Firefox/17.0
Build ID: 20121120063346

Steps to reproduce:

Upgrade to Thunderbird 17.0 (Nov. 20, 2012) from Thunderbird 16.02 (All from official release channels; Ubuntu software updater). Then update from Lightning 1.8 to Lightning 1.9. All this on a small screen computer (e.g. netbook)

Screensize of my netbook (Samsung N220 Marvel Plus): 2.048 x 1.536 Px


Actual results:

A fully functional Thunderbird opens, that cannot be maximized, and that is missing a "Maximize" button (see Screenshot).


Expected results:

Even on small screen netbooks, Thunderbird should be able to maximize like in the previous software configuration (TB 16.02, Lightning 1.8)

Thunderbird 17.0 apparently has updated "minimum width parameters" (sorry, newbie language), forcing the application to disable the maximization feature on small screen computers. I have Ubuntu 12.10 running a small screen netbook, and after attaching an external monitor, maximization was possible.

Furthermore, the maximization issue doesn't occur when Lightning 1.9 is deactivated (without external monitor), as the addon apparently requires further width on the screen (maybe even the addon has updated "minimum width parameters"??).

I don't know about any minimal width requirement. On Win XP, TB can be resized down to about 200x100px window size.

If your netbook screen is 2.048 x 1.536 Px (but that are not the dimensions of the attached screenshot) you should have no problems. Maybe the Ubuntu window manager does hide the button?

Or try double clicking TB title bar to maximize it.

I have solved this issue by decreasing width of Lightning 1.9 in TB. I have no idea if such things as "minimum width requirements" exist, I just used the term to find out if therein lies the bug. With a little tinkering (decreasing width of Lightning 1.9 in TB), this bug is irrelevant, but it took me a few days to figure out. I found this so annoying I actually figured out how to use this bug reporting site, so this should definitely be fixed. You can easily reproduce this annoyance on a Samsung Marvel Plus (my netbook, and probably any netbook with equal resolution/screen size)

OK, then. It looks like the buttons now moved to the top menu line, separated from the TB window. Looks like some strange ubuntu specific window manager. Also I think you use the Ubuntu TB version not an official one (there is the Global menu bar integration extension).
I am sure 1024px is enough width for Thunderbird.
From my tests there is a hardcoded minimal width but it is 350px on Win XP.
