I seem to be having a problem with the Presentation tab in OpenLP1.2.4 using Vista - it is permanantly greyed out. I am using powerpoint 2007 and also have powerpoint viewer 2007 installed. Both of these seem to be working fine - however I have recently reinstalled the viewer. This morning when I first ran OpenLP it came up with a powerpoint error (sorry I can't remember what it said) but that has not repeated since. I have tried running powerpoint and/or the viewer before running OpenLP, but this does not seem to help.
Oh I should also add that using 2.0alpha (which I downloaded a few weeks back) it seems to work just fine.
