Adobe Protected Mode and App Container

The primary cause of this issue is Adobe having protected mode enabled during startup. In newer versions of Acrobat this can also be caused by "Run in AppContainer" being enabled (sometimes updates to Acrobat will re-enable these settings automatically).  You can turn protected mode off on your workstation using the settings in Adobe Reader.

To disable protected mode in Acrobat/Reader 9:

In Adobe, navigate to Edit-> Preferences

Select "Security (Enhanced)" on the left hand navigation panel
Uncheck 'Enable Enhanced Security'
Close and re-open Adobe

To disable protected mode in Acrobat/Reader X:

In Adobe, navigate to Edit-> Preferences-> General

Uncheck 'Enable Protected Mode At Startup'
Close and re-open Adobe

To disable protected mode in Acrobat/Reader XI:

In Adobe, navigate to Edit-> Preferences-> Security (Enhanced)

Uncheck 'Enable Protected Mode At Startup'
Close and re-open Adobe

Note:  We have seen some cases where a log out and then log back in was required for this change to take effect for Adobe XI.

To disable protected mode in Acrobat/Reader DC:

In Adobe, navigate to Edit-> Preferences-> Security (Enhanced)

Uncheck 'Enable Protected Mode At Startup'

Uncheck 'Run in AppContainer"

Close and re-open Adobe

Monitor Manager Applications

Another cause of this issue is if the user has a Monitor Manager application installed.  These are applications that make it easier for users to move Windows between monitors.  If you are using one of these applications, please turn it off, then close and re-open Worldox and see if your issue is resolved.
