I have this issue:
1) I start Visio
2) Select default document template "Basic Diagram"
3) In this fresh document I add a basic shape to page
4) "Shape Styles" ribbon shows SPINNING DOTS on all thumbnails and Visio goes into freeze "Not Responding"
5) As a by-product of above issue - all the shapes in left "Shapes" palette display in ugly Black and White coarse jagged line thumbnails instead of the smooth blue shape icons that match the blue look of the Theme selected for this document
- deleted all files in AppData\Local\Microsoft\Visio - suggested in another thread here
- tested various settings in Visio
- reinstalled ALL MS OFFICE PROGRAMS !!! (Complete Office and Visio uninstall and install)
Thank you for any suggestions
