Hello.
LiteStep has a problem with audio and video. When I right-click, after 2 secods, the audio/video is playing just stops. I tried this with Windows Media Player, Winamp, KMPlayer and BSPlayer. I'm usind KDE theme. It's theme bug or LiteStep bug?

Right click on what?

I think he means his Popup, dev

nunoabc,
Try changing themes first.
It might just be the popup module that is being used in that theme.
If it works correctly by changing themes and you really like that theme you may try updating the popup.dll file to a newer version and see if this solves your issue.

good luck
