Same behaviour ;).

No, there is a "more" installed in /usr/bin/more and that works fine when
invoked through the command line. For some reason the plplarse routine seems to
try and start a bare-Windows command: "c:\program" in the error message is just
the start of the directory name under which commands and programs can be found.
A workaround would be not to use this feature on any Windows platform.

Why exactly? They have similar functionality, don't they?
