Ok, the Google ad will not show on the home page or category page, only on topic pages. Scripts from another ad provider does not work and the side will not load. The HTML widget, me thinks, should be able to render any HTML/JS script.
Depending on the theme you are using you can change their locations in the template files. For example for lavender just move this between line 1 and 2. Would have to do it for the other pages as well like categories.tpl etc.
I'm running v0.7.2
I'll check on my testing account.
Sorry, after checking through my group's permissions it has seemed to remove all those permissions. My guess would be that I recently renamed my group from 'Mod' to 'Staff'. I think a neat feature would be global permissions, so rather than me having to go through my twenty odd categories, applying all the permissions, I can just give site-wide permissions to a group.
I solved my own problem... I setup a custom notification to fire on the action:post.save hook and I was using the same default standard format for the notifications nid value. Basically I was firing off a notification with the same nid as the notification that auto generates when you post a new topic.
