After upgrading to 1.5.3, I've noticed some odd behaviors. My link & blockquote quicktags require clicking on them twice in order to activate them. On first click, the quick tag grows smaller & moves left. On second click, the quicktag action is performed. I've also noticed today that sometimes if I click the Save & Publish only once, nothing happens. If I click it twice, then it saves.
Anyone seen this odd behavior &/or have any suggestions on how to approach it?
