Every time I am working in Illustrator & switch to a different app, Illustrator will hang when I return causing me to wait prior to returning to my work. So, for example if I am working on an illustration then go to google chrome to look at something online then return to my work in Illustrator it will hang & become unresponsive for a little bit of time (1 - 2 minutes) after waiting I can continue to work . I have already followed the steps outline by Adobe (found here: https://helpx.adobe.com/illustrator/kb/optimize-illustrator-performance-windows.html) to increase performance within the app & it has not alleviated any symptoms. Illustrator does works well when I am in it just to note.
My system specifications:
16GB of ram
Adobe Creative Cloud
Adobe Illustrator 22.1
by no means is my system not capable of handling the tasks thrown at it.
