I have a Windows 10 toshiba laptop. Sometimes when I'm drawing on photoshop CC, it stops responding, and if i shrink the window, i can't open it again. When i hover over the little photoshop icon it shows the little photoshop screen above it, but when i click on it (this should take me to photoshop) it disappears without opening. It eventually lets me open it again after about 20 minutes but it's very very frustrating. Any ideas on how to fix it?
