Alice is the Worst Software I have ever used!

moving the camera to an object option is hit and miss at best! how am i to interpret these errors? i might be able to interpret a gcc error about my code, but these arcane program errors are proof of the amateur nature of Alice itself.

this is simply unacceptable and Alice should never be used in the classroom except by computer science majors that are fixing this program!

nice it simply crashed without any warning

[jediaction]

Yes, it sometimes happens, but they are fixing those problems slowly..

i don't want to come off as someone who overly complains, but i suppose it's part of the devel process. i have to use the program for a class and sometimes get frustrated. of course there where no color syntax highlighted programs i was aware of when i took C an epoch ago. here is the latest bug.

clicking undo in a boolean string variable == yes in alice

the error is too long for this forum - i should put this in the bug reports i suppose

Alice version: 2.2 09/10/2010
