Adobe InDesign CS6 is not operating properly
I just updated my Mac to OS X El Capitan. I have Adobe Creative Suite CS6 on my computer. After the Update, I noticed Adobe InDesign CS6 was not working properly. For example, editing a paragraph...As I am typing in the paragraph with 3-5 sentences, text inside the text box disappears. The only way to bring the text back is click out the box and zoom in and/or out. Another glitch is that a window will pop up stating I am out of memory. This glitch never happen before the update. Can some tell me what I need to do to correct these issues?
Mac Pro, OS X El Capitan (10.11.5), Adobe CS6
