Add focus/Modify Focus doesn't work
I've seen this posted before but not seen a good answer. I have a trial version of PSE 15.0, 20160905.m.97630 x64 on Win 10 Pro, 64 bit. Toshiba Satellite laptop, 16GB RAM. I tried resetting general preferences, though I had never touched them. In Guided Edit, in the zoom burst effect the add focus area button doesn't work. Similarly, in the tilt shift effect, the analogous button, modify focus area, doesn't work. By doesn't work, I mean nothing happens when I click the button and draw a line on the photograph as directed. I'm pretty sure I'm using the tool correctly, as I've used it in several previous versions of PSE. TIA,
Rick
