Re: Fwd: [libreoffice-users] Re: LibreOffice-Base CPU usage

Hi :)
Ahah, thanks Jay.  I was hoping that HSql only dipped into using java for a few things.  So, Don 
needs to have that java box ticked all the time he uses Base and can only avoid it when not using 
Base at all.

Is it possible to edit short-cuts and stuff so that opening Base will enable java but opening java 
wont?  I think it might be possible in Gnu&Linux by having 2 different short-cuts on the desktop or 
in the taskbar/panel.

regards from
Tom :)

The HSQL engine is Java based. It may be possible to use Base as a
front-end for something like MySQL or PostgreSQL, which do not use Java.
