Hi, I just downloaded tkgnuplot, hoping I could use it to write a little frontend for gnuplot. It stopped with the message "The fork() function is unimplemented on this machine" (Ruby 1.6.8-8 on Win2000) Searching the archives for an answer I found, that "fork" is in fact not implemented on my machine. Has a solution been found or is anyone at least still looking for one? Is there a simple way to change a program (replace "fork" by "thread" etc.?) so it runs on Win? Thanks! Ralf.
