Play button sometimes grayed out after pause

[brittney24]

in 0.8.0, especially if start a video by sending it from an Explorer folder to SMPlayer, often the play button is grayed out after the video starts (video starts immediately after "sending" it to SMP from Explorer). When use the pause, the play button is often grayed out. The way to start play again is press pause. Sometimes this then causes play button to be activated after repressing pause (once), sometimes not.

Usually - if pause & resume play by pressing pause button enough, the play button eventually becomes active.

Tried default GUI / style / icon set & several other combinations. Didn't see any difference.
