Bug #: 31854
           Summary: Wizard101 launcher slow to load and then freezes for
                    30 seconds or more
           Product: Wine
           Version: 1.5.14
          Platform: x86
        OS/Version: Linux
            Status: NEW

          Priority: P2

In 1.5.14, the Wizard101 launcher takes 5-10 seconds to even appear (used to
take 1-2) and the login screen then freezes for 30 seconds or more (if it goes
over a minute I just kill it). The problem is particularly bad if my connection
drops while playing (not a Wine issue; my DSL is flakey) and I have to close
the game and login again--sometimes I have to kill and restart the launcher
several times before it will get past the freeze.

A regression test identified this patch:
