Hello, I have been working for several weeks with gtkwave 1.3 and 2.0pre. My summary is, that version 1.3 is more stable and robust for the daily work. But on the web page, there is only version 2.0 mentioned. Ales, may be you can add also a link to: http://home.nc.rr.com/gtkwave/ and mention that for newbies it is better to use version 1.3. Peter
