The last few days while trying to get on RCU, it's been loading very slowly and then when it's almost loaded I get a security warning window asking me if I want to install and run macromedia flash player. What is up with this window? I've never had this happen before, should I install it ? or just keep hitting the no button? Is this just for RCU? because the only time this window appears is when I'm trying to access RCU
