Hello, I have two problems:
1) when i click on the effects' directory, this not expand so i don't choose the effect.
2) when i apply a saved effect this not work.

Thank you for answer
Lorenzo

1) There were problems with this on some configurations, but it should be fixed in 0.7.9: http://kdenlive.org/mantis/view.php?id=1827
2) Does it not appear in the effect stack, or does it not have any effect on the video?

not have any effect on the video: kdenlive crash
