When working on large signal flow drawings, Visio freezes with every shape or drawing move for 10-30 seconds at a time with the "Not Responding" message every time. I have un-installed, re-installed, turned off the "Show text suggestions as I type", "disables graphics hardware acceleration", updated my graphics card, added RAM, and just bought a new PC with better specs all around. The problem remains. I have drawings due for projects and Visio is literally un-usable. Spent 3 hours on a drawing that would normally take 15 minutes tops. Is this a Visio scripting issue like I have read? I really need a solution. Thanks!
