And if it was, was that annoying slowdown bug ever fixed? I recall talk of someone fixing it but I don't recall it ever being released.
Yes, this guy was me (and Progi1984)!! I have a version of gnet running without any slow down, using the ETNA library (see my sig for details). This is very simple to use, and presents no slow down at all. This works for BlitzMax (windows only) and other Blitz (3D, Plus, 2D).
Since you are asking :-), I will release this ETNA-gnet very soon, before this week-end. Stay tune!
