While editing a Software package the Java runtime and applet startup is slow.
Java is running verification of trusted code vs. sand boxed code. Depending on the environment this can take a minute or more.
On the client used to open the Symantec Management Console open the Java control panel.
In the Advanced tab set the Mixed code to disable verification.
Restart the internet explorer and the Java runtime should start faster.
