Please, Adobe, advise: when will this be FIXED? Users having to clear cache as a 'workaround' is not acceptable, especially when a user trying to get work done gets stalled by this totally illogical (i.e. non-computer, i.e. not the fault of the PC but the software) behaviour then has to stop their workflow, hunt down a solution which is NEVER easy (thanks to the million ongoing changes in the software between every version (why???)) before they can become productive again? This is CLEARLY not a professional solution so I hope Adobe is looking to fix this approach going forward?
