I've installed the version 0.0.6 now, but the program still shows 0.5, when clicking on the info button.
And the videos are lagging like hell now, everything was running smooth before :/

//edit : unticked frame drop and it's running smooth now.
And the "zoom to fit the screen" function is really usefull, no black bars anymore finally.
But the programer really forgot to change the version number in the info tab.
