Bug ID: 35150
           Summary: Battle.net App can't open drop-down for language/realm
                    list
           Product: Wine
           Version: 1.7.8
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
    Classification: Unclassified

What I do:
I am starting the Battle.net App Beta in order to install the Diablo III 2.0.1
PTR. So I switch to the Diablo 3 Tab and click on the arrows to change the
"language/realm" to use above the "install" button.

What happens:
Clicking the arrows doesn't do anything.

What happens on Windows (should happen):
Trying the same on Windows this opens a drop-down (going up actually) with the
realm selection.

There is a Workaround:
I can click on the realm ("American" per default) and then use the up/down
arrow on the keyboard to switch through the realms.

Log:
Whenever I try to click on these arrows my terminal log fills with lots
(dozens) of these messages (no others in between):
fixme:uniscribe:ScriptShapeOpenType Ranges not supported yet

I am running wine git version from 2013-12-15 and applied the patch in
http://bugs.winehq.org/show_bug.cgi?id=33947 to not make the program crash
after 15 seconds. The problem also appears without the patch, though.
