Whenever I use the "select and mask" in photoshop, after a couple minutes it stops responding and I have to close photoshop and restart it! I don't think I have EVER had that issue when it was refine edges! I don't know what they screwed around with when they changed it, but ever since I have problems with it! like they say "if it ain't broke don't fix it!" I have an 8 core processor and 16 gb of ram. The GPU is an AMD Radeon HD7800. I should NOT be having these problems!
Mac, Win? Photoshop version?
Windows 10, photoshop 2015.5
You might try installing the newest version - CC 2017. When you install, be sure you expand "advanced options" and uncheck "remove previous versions"
