Hi, strange issue here, which is intermittent but very annoying. Using latest Safari (6?) on ML. I usually have 6 or so tabs open, all going swimmingly, when suddenly they all cease to reload if asked, or update. Clearing cache doesn't seem to work, only restarting the mid 2011 iMac helps. A real pain in the ass if you are in middle of a financial transaction or the like. Anyone else got this or have any ideas on how to solve it?
