I am running Win 7 x64 and ODP does not work. I can't create new or change any themes even when I can it only lasts until I log off or have to reboot for what ever reason. Even when I start from scratch and save it under a different name, when I go to check it out later it will load as what ever theme I had running at the time I created the new one. I've un-installed and re-installed several times and I always get the same results. This is really bad (for me) since I use ODP extensively for all my needs and losing the use of it is a major bummer. I hope that these things are dealt with in the next release.
