Re: [Plplot-devel] Problems with installed plserver

[Vince D. <vi...@sa...>]

Actually I can't really see what could be going wrong... may have to leave
this up to Geoff etc to look at.  However I will continue to think.

I the long term it would be much better to get rid of the compiled
executable that is plserver and replace it with an executable Tcl script
which simply loads dlls etc.
