Upgrade went reasonably well, but I cannot now use the left tabs in the admin/catalog/manage products section. I can click on a product to edit, but cannot select from the tabs on the LHS.
Edit: tabs work in Firefox, but not Chrome.
Edit 2: it’s all the tabs, eg Category Products won’t work, in Categories.
Edit 3: I see there’s a closed bug track issue on this already, sorry. Shame though, I’m using Chrome exclusively now and it must be a conflict with something in the new version.
