Symptoms
After upgrading the Citrix client software to the latest Receiver 3.x version, the customer noticed that intermittently, Published Application seamless windows are losing focus and staying on top of other windows even though they are not the active window.
The issue was not seen with previous Citrix client versions (e.g. version 11.x and 12.x)
Cause
The issue exact cause is unknown, but seems to be related to changes in the gain focus behavior of the new Citrix Receiver 3.x
