Firstly, many thanks for getting this going on OSX! I think it was just bad timing on my part that I changed over to a Mac at the same time as Apple updated their OS causing this to stop working (it did cause a problem when I was doing words at church, forgot my laptop's power lead and the battery ran out half way through the worship...)
Anyway. With the latest version, I have come across a couple of bugs - I know none of the development team run OSX so don't think I'm having a go, I'm not! These problems might be systematic across this version of OpenLP, but as it's only been available for a few days it might not have been noticed yet.
The first one is when adding songs. When I come to add an author, if I type an author in (rather than selecting from the dropdown), it always tells me that it's a new author and needs adding, no matter whether they are in the list or not. If I cancel, then re-add (without making any changes), then it goes in fine. (Additionally, is the confirmation to add a new author necessary? I suppose it makes sure that it is spelt correctly and adds a bit of standardity to the list...)
The second problem is when importing songs. I did have problems with 1.9.7 with this as well though, but without checking 1.9.8 on my PC (which is currently around 100 miles away) I couldn't tell you if I am still having problems. I have OpenOffice.org installed on my Mac, but OpenLP cannot recognise this in order to import from it.
Anyway, like I said, thanks for getting this going (I am telling people about it too by the way, would be good to see this starting to get out there!). As none of the dev team use OSX, if I do come across bugs do you want me to put them here or on the bug page? I'd offer to help out with dev, but unfortunately I'm very behind with programming languages, and (other than PHP) the only one I know is the ancient VB6!!! (and of course, now I'm on a Mac, even that is pointless...)
