I have been using Elements 12 for about 2 weeks and have found that the editor becomes very slow when using several tools such as cloning and magic selection. Since these are some of the basic functions, I am finding elements 12 very frustrating and almost unusable. I am running the software on a Mac Book Pro running Maverick. The Mac has an AMD Radeon HD 6750M graphics processor enabled. Is there a software fix or a configuration to fix this type of problem?
