Re: Re: Mathematica 3.0 & MathReader 4.0

I have not got MathReader here to test this, but I believe that the problem
is that both Mathematica and MathReader use the same file signature, OMEG. I
think you can probably solve this problem as follows. Use any one of the
many utilities which let you change the attributes of a file (type, creator,
etc) to change the creator ("file signature") of MathReader from OMEG to
something else (e.g. GEMO).  (For example I use the shareware program Snitch
but there are countless others, including both freeware and shareware).
MathReader will then loose its icon and assume a generic application icon,
but will continue working as normal. However, all files with a Mathematica
icon (signature OMEG) will now open, when double-clicked, in Mathematica.
