Very dissapointed so far by this adobe soft, that I just installed a few hours ago. At this point it is worthless and no way I can use it like that . After installation I went directly into the editor and right away I saw that the software was very sluggish with my cursor dragging . After clicking on a top menu (File) the menu bar open (5 sec.)and if I scroll it down I do not see the blue color following my cursor, and if I click at the location in the bar of my cursor it takes a few second before it respond. I am also using the following adobe softwares that works flawlessly : Photoshop CS5.5 extended; Bridge; Camera Raw; Lightroom 4.2. My computer uses an Asus P7P55-E Premium motehrboard with Win 7 pro 64 bits with an intel I 860 2.8 mhz and 8 gigs of RAM. All my adobe softs are 64 bits, except for elements 11. After seeing that, I installed the upgrades without any visible problems. Even after that nothing has improved.
I have to say that I have quite a few softwares installed that all work perfectly such has Topaz bundle; Photomatix pro, etc. In fact of all my softwares this is the only one that is giving me troubles.
I hope somebody has a solution for this extremely poor behavior.
I think you are using Win7, if yes please try the following
Right click on the PSE icon and select Run as administrator
Now try to use it, check if there is any change or not.
