Ah, I'm so glad to hear that! I put the warning partially because I like flashy gifs and bright colours, but it's good to know that so far nothing causes issues :)
Oh, correction: the original 1989 Kid Pix was always public domain and intended to be, given Hickman made it because he saw his then-3-year-old son struggling with MacPaint, so he wanted to make a free art software that's easy for kids to use. ;3; His friends encouraged him to sell it, Broderbund picked it up, and 1990 onwards, those versions of Kid Pix are copyrighted!
It's a very beautiful site with a soothing and calming atmosphere! I wish it could be kept up archived, but...
I just saw her post. Very sad! Hopefully it will be majority archived on the Internet Archive
Unfortunately, her website seems to be exempt! I tried to archive and it said her domain is exempt... seems like it didn't allow archiving somehow.
