wxMaxima does not read maxima-init.mac



I am running wxMaxima 8.5 on Ubuntu 10.10.
Maxima does not appear to read maxima-init.mac located in my /home/ron/.maxima folder or in any other folder.
Is there a preferred location for wxMaxima other than the .maxima folder?

Also, is there any documentation on editing the .wxMaxima file in my home folder?

Many thanks
