I decided to learn a bit about Amapi 5 (the one that comes with C3, version 5.15w once the patch from Eovia is installed) in order to be better prepared to work with Amapi 7 once C4 is out. I can't do the Amapi 7 demo cuz I allowed the 90 day timer to lapse. hehe. After going through a few tutorials I've stumbled into enough little bugs in Amapi 5.15 to make me not want to touch it, i.e. numeric input and names being invisible, Workshop icons superimposing themselves on each other, even selecting points with the 'bullseye' is not consistant. Are there fundamental bugs like this in version 7? I don't think it's my system, although I guess it's possible. I'm running XP Home, P4 2.66, 1g, 128m vid, 180g hd. I run a lot of other 3d apps and have no 'bug' troubles with them beyond those that everybody else has, too. I don't really want to bother with C4 Pro if Amapi 7 is this buggy. Thanks for any feedback.
