Hi Gordon,
Indeed some given examples are wrong for windows and also the Macro
Path is not searched for rootlogon etc... in ROOT 1.03/04.
However, Fons told me to fix it in the next version.
Below follow the .rootrc & co. I use under win95 which work
Note : they should be located in your %HOME% directory, which
in my case is c:\nick.
In the next ROOT version it should be possible to replace c:\nick
by %HOME%.
Cheers,
Nick.
