Just installed SS3 on my server - no problems with it.
However, in the CMS Admin I am setting up my page structure and I'm getting some issues...
I have a page which contains sub-pages (child pages).
When I Save & Publish the Parent page the sitetree reloads and the "dropdown / expand" arrow to the left of the page briefly appears, then disappears, so I can no longer access the child pages unless i reload / flush the admin.
Its driving me crazy - please help! Making things pretty unusable...
I'm not sure if I've explained this well, so see screenshot below!
