Actually, the pop-up window should not pop up even in the current version. Could you please check that the script you are running to start Aware IM Control Panel has "-d" option ?
For example,
start %JAVA_HOME%\bin\javaw -Xmx96m -Xms20m -cp %CLASSPATH% com.bas.controlcenter.ControlCenterApp -d
(note -d at the end)
