FortiClient interferes with Deltek Ajera

FortiClient 5.2.6.0664 and newer

Hello, does anyone know how FortiClient might be interfering with Deltek Ajera? The trouble comes when following a link (Time & Expense) that produces a pop-up window just prior to opening a new browser window. Uninstalling FortiClient allows Ajera to work normally. Nothing in FortiClient logs and no indication of anything being blocked. Thanks -Steve
