[michelle23453053xjps]

Hi, ive updated photoshop to the latest and the top menu bar with file, edit, image, layer etc, works for a little bit then it becomes unuseable, it goes sort of blurry and is unclickable, i then cant finish work and is making photoshop completely unuseable. Any tips or has this happened to anyone before. Thanks in advance for ur support.

@michelle23453053xjps try manually resetting your Photoshop preferences

Remember to back up your settings before doing the preference reset

Thank you for responding. 
I'm still having issues, I can not get the photoshop preferences once I quit photoshop, as I can not find them. 
I keep going in a circle and go back on photoshop, and find the preferences in setting, I then can click  photoshop, then settings, general and have tried "resetting preferences on quit" but nothing is changing. 
I've attached a picture of where I'm ending up as I can not find how to get to the links you have sent me. 

thanks again
