Winplot maxes CPU

Hi fellas

I have been running the brilliant plotting software Winplot (http://math.exeter.edu/rparris/winplot.html) on my Vista box for several months now. But suddenly today, it refused to start. When I execute the program, it shows up in the processes list in task manager, but the program window never appears. Any idea what could have gone wrong? Could any of the automatic updates over the past few months broken the compatibility? Running it in compatibility mode for Windows XP doesn't work either (same problem).

Thanks for any help in advance.

Hey Tanmoy,

Just use System Restore and go back a few days and it should work but if it happens again or fails let me know

cheers
