wxMaxima does not read maxima-init.mac



All,
I need to clarify my question. 

It appears to me that wxMaxima under Linux does not allow Maxima to automatically execute maxima-init.mac. Is this a correct observation?
As stated previously my maxima-init.mac file is in the default userdir pointed to by maxima_userdir (/home/ron/.maxima). 

I tried the load command "load(maxima-init) and get the following error:

Maxima encountered a Lisp error:
 Error in LET [or a callee]: ((MPLUS . #0=(SIMP))
                              ((MTIMES . #0#) -1 $INIT) $MAXIMA) cannot be coerced to a namestring.
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.

I copied the contents of maxima-init.mac to another file (x1.mac) which executes without error. This leads me to believe that there is some conflict 
with the filename maxima-init.mac and wxMaxima.

This leads me to another question regarding documentation on the format of .mac files. I would appreciate help in locating such.

And, finally, I'll repeat my last request from the previous email for documentation for the .wxMaxima file in my home folder.

Thanks for your patience.
