I just downloaded the trial version of Elements 11 to see if it was a performer. While open, my hard drive is constantly thrashing even with no image opened. I've not got a doggy machine as it has a 64 bit Windows o/s, 32GB of memory, an intel core i5 processor at 3.1ghz speed, and 403 gb of free hard drive space. Does everyone's hard drive have a steady heartbeat drum when using this version? I do not experience it with Elements 9.
