2017 and Photoshop cc 2018 having issues using the rectangular selection tool with free transform; cant pull handles to expand or reduce selection. the patch tool wont work and radial gradient non responsive in Camera Raw. I have a high powered machine with 64gigs of ram and a 1tb scratch disk. What is the issue? I have an two systems files and text the adobe tech captured to share with the engineers. the whole problem started after a heat related crash killed my motherboard and after the replacement the brushes had become sluggish and then they stopped altogether. I constantly update the graphics driver and have two cards.
