           Summary: QTMovieWinTimer logic inversion
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: eric.carlson at apple.com

The Win32 timer used by QTMovieWin has a logic error that causes it to always
use SetTimer(), even when the callback interval is below USER_TIMER_MINIMUM. A
side effect of this is that the movie timer is sometimes blocked for
significant amounts of time because (low priority) WM_TIMER messages are not
processed when the thread's message queue has any higher priority messages, and
WebCore/Win's timer uses (high priority) PostMessage for low interval timers.
