I seem to be having some issues with Quicklook, one of which at least Ive managed to solve and the other Im not sure that there is a fix for.
First of all, some of the quicklook effects as demonstrated in the Apple videos were not working. For example when I had a Keynote presentation visible in coverflow, if I moused over it, I did not get the icons to page forward and/or back, the same for powerpoint and so on.
I found out that for Keynote at least, I need to open the presentation, tick the box in the save dialogue that says "save preview with file" and then resave it. Afterwards in coverflow, this provides the aforementioned page arrows. I just hate the thought that this is something that needs to be done for all documents, surely its more simple than that and Ive overlooked something?
The other thing that I dont think works, is full screen mode as when I view the presentation fulscreen in quicklook, its formated like a giant page that you scroll down, not individual slides that you can move through with the arrows or one after the other (unless you use the slide navigator). I dont know at the moment though if this is just me, my system or the way its supposed to be as I dont have anyone to check it with.
