I installed Parallels 13 last night and now QuickenWindow will not display any screen for Quicken 2015 Home & Business. If I select "Show All Windows," what I get is icons for my various Quicken backup and data files. I can click on any one of them and QuickenWindow still won't display a Quicken screen, even though the macOS task bar shows Quicken is running. I decided to reinstall Parallels 12 in hopes that it was a version issues. No luck. I have v12.2.1.
Thanks, Arun. Switching to Coherence solved the problem. Once I could view my screens again, I could leave Coherence and still access them.
Glad to know that you were able to sort out the issue. Please get back to us for any further queries. Thanks!
