Fix for at least three subtitle services.
FileBrowser was going behind the DialogSubtitles.
No need of having zorder = 2 in the DialogSubtitles. It would produce the bug on the FileBrowser.
Services are LegendasDivx \ LegendasZone \ Pipocas.
I'll fix the pull request on the gotham branch too.
Merge pull request #632 from highlandr/gotham
