When I double-click on an Adobe Illustrator file to open it (without Illustrator already running) if there are fonts in the document that need to be activated by Suitcase, Illustrator crashes right after the fonts are activated in Suitcase. The error message that is displayed is “Adobe Illustrator 2015.3 quit unexpectedly”.
If Illustrator is already running when opening the same document, it does not crash and the fonts are activated as expected.
The key factor here is that if Illustrator is running before the document is opened, no crash. If it is not, it will crash.
I have tested this in two different environments with two different operating systems. The behavior is the same on both.
I had previously used Suitcase 6 with Adobe Creative Suite 2015 in one of the two environments I tested. This behavior did not occur.
- Suitcase 7 Ver: 18.1.0 (1042)
- Adobe Illustrator Ver: 2015.3.0
Tested in both environments:
- New stock build Mac Pro (Late 2013) w/ OSX 10.11.5
- MacBook Pro (Retina, 15”, Mid 2015) w/ OSX 10.10.5
