Q: When I launch PDF Studio on my Mac and then try to use Mission Control, all windows disappear instead of displaying in mission control. How can I solve this issue?

A: This is a known issue and has been fixed since PDF Studio 12.0.2. Please update to the latest version of PDF Studio.

If you’re using older version of PDF Studio, please follow the instructions below as a work around:

Go to Device settings -> preferences, select Mission control and check the “Group windows by application” option.
