Just to know I've done everything I can to avoid problems with Java: I have detailed the settings below:
Java Control Panel:
Network settings: Use browser settings
Temporary File settings; Keep temporary files on my computer
Disk Space: Select the compression level for JAR files: None
Set the amount od disk space for storing temporary files: 32768 MB
Notify me before downloading
Check for updates automatically
Advanced settings: Daily 7 pm
View and manage Java runtime version and settings for Java applications and applets: Greyed out
Enable is unticked
Security level for applications not on the Exceptions List: High. (Unable to set at very high with the radio button)
Exceptions site list: Do I need to add Freemind to this as it's a desktop application?
I have not done anything on the list.
