This is new to me in PS. I have CS6 registered and a few years with updates etc. Whenever i now try to "save for web", i move the cursor over the boxes to choose (jpeg/gif) etc but then, yellow text info boxes start appearing on screen and just wont go away? Even when i cancel and return to the main workspace? I have to totally exit PS to clear the screen (those yellow boxes stay around untill i shut down PS totally). I enclose a screen shot. I have Mac OS High Sierra 10.13.1 with 16Gb memory and up untill lately, things have been ok. Is it static, memory or what - its only when i click on "save for web" ?
