Compatibility issue with FM5 snippets


i have observed so compatibility isues with snippets from FM5. The slideshow is created by using FM5 and snippets from this version.

Now i try to open this slideshow with FM6 and the snippets do not work like they did in FM5. For instance the snippen Wischer should only be visible for few seconds and then dissapear but the text stops at the left boarder of my screen and is still visible.

A workaround ist to replace all faulty snippets but this is a lot of work.

I there an other way?
