I am not sure what is going wrong, Johan, but I have never seen anything like this before.
I have been using Premiere Elements on my Mac for a year. It always defaults to the last project settings I used.
Somewhere on the system there is a textfile with settings. In this file I can change things: ntsc into pal, for instance. PE9 then opens in pal, but also overwrites this settingsfile immediatly and then my changes are lost.
Maybe I should consider a re-install?
I am not a Mac-person, so you might have to help me a bit with Mac-speak.
Some Mac users have had to reset their Permissions. From what I gather, this is a bit like running as Administrator on a PC. IIRC, this needs to only be done once, and then the Permissions setting can be reverted, but it clears up a lot of similar issues. If I can locate the exact comments on doing this, from the PrPro forum, I will post a link.
Wish that I could speak Mac better.
[Edit] Here are the steps for fixing some odd, but similar issues in PrPro CS5. They look very benign, but study them, just in case:
If you're on a Mac, here's what you need to have your tech support do. Log on to your ROOT user, load Premiere CS5 and open a project. Then close the project, boot into your user, and you should be good to go. It's an issue with Mac Permissions files that (for some reason) gets fixed by logging in as a ROOT user and running Premiere once. This should only have to happen once.
