CC 2017 Slow with any placed images Constant Beach Ball
When I place Illustrator or images, Indesign slows to a crawl. The beach ball constantly comes up hampering work flow and causes frustration. This never happened in in CS5, and if I could use CS5 I would still be, but unfortunately CS5 does not work with Sierra. I think it might have something to do with the CEPHtmlEngine. When I quit Indesign this engine collapses too every time. It doesn't collapse on other programs.
Also Illustrator images that have fades to transparent or masks don't show properly in Indesign. A white background around the area that fades appears. If Photoshop masks faded to transparent, there is no reason Illustrator files wouldn't do the same. This has been a major issue for a while now.
