Occasionally the check boxes after each PM in my inbox and send folders disappear so that I have to open each PM to delete it. Also they are sometimes missing in Advance Search so I can't select Post, All Types, Blogs etc. I'm using the ECF-1 skin with google chrome. This has been happening for a week or 2. I've tried refreshing the page to no avail. They eventually come back on their own but this is quite annoying. Has this happened with anybody else and is there a solution?
