I have found that Spark hangs when user logs off windows. Only occurs if main window or logon window is open. Does not seem to happen if only tray icon is active.
Spark.exe seems to consume full CPU (100 percent of one core...)
are you using the JRE that is installed in your OS and is this a version Java 6 u25 or above? This is a known issue of the JRE together with Spark. There are as far as I know three options:
Use the Spark with the build in JRE. This is working but may be considered a security issue. However, the Spark JVM should only be used by Spark and this may be less of a problem since the JVM i snot used for applets in a browser.
Upgrade your JVM to Java 7. As far as I know, the Java issue is not existing in J7.
Downgrade your OS JVM to Java6 u 24. This is not seriously an option to to security riscs for the whole system.
