answer:Yes, I’ve long experienced this. This is one of many bugs, bad design elements, and instability issues of Adobe’s software. Three or four months ago, I switched to Pixelmator. Many would call it a downgrade, but I couldn’t have been happier with the change. Though many techniques might take a few more clicks (but some less), I can do pretty much everything I did with Adobe Photoshop. To solve your current problem, I’m not sure what to tell you. Just… don’t close it as often. ;)
