I have a problem with Adobe CC 2018 suite with Citrix Xenapp. Adobe CC 2018 applications are published applications published in the VDI session. When I want to start using Adobe illustrator CC 2018 or other adobe applications, for example Adobe illustrator application is taking focus over monitors and I can't switch between local applications from the taskbar. The issue occurs with one monitor or multiple monitors. It means that illustrator is opened on one monitor and some other application is on other monitor. At this moment it is not possible to switch between applications or work with other application on the other monitor. so far we have found a workaround for this issue and that is the alt+tab combination. After using alt+tab than the issue is gone for the duration of the VDI session. New VDI session is repeating self.
