I'm running Premiere Pro CC 2015.2 on a early 2008 MAC Pro 3.1 (specs below)
Premier runs OK, until I hide Premiere Pro CC 2015.2 and go temporarily to and other app: e.g.: Media Encoder, Photoshop, etc. . When I return, whatever the first action I take brings up the "spinning beach ball" If I leave Premiere alone, eventually the beach ball goes away and Premier is back running fine, which could take more than an hour. Normally, I have no time for this, and I just force quit Premiere and upon re-booting, and the project will come back fine, and I can carry on.
It started relatively recently, but I only recently recognized this as a the symptom. The only thing I have done recently to the Mac Pro was to upgrade to El Capitan 10.11.4 (not a clean install) from Yosemite.
It's an odd problem, and it's getting more annoying every day. Any thoughts on what can cause this? As ever, your help and experience is greatly appreciated. Thank you for your time.
