:mad:I've created a Group for Students and assigned those EXACT same permissions and it fails. If I give Change permissions, everything works. If I give Students READ access to the folder, an Creator Owner MODIFY permissions it works, of course now students can modifiy files that only they create. When I duplicate your screen shot w/ permissions I get a message that they do not have sufficient writes to save a file...
I know it's not rocket science, but .... ugggh!
I've gone into advanced properties, and modified the permissions to match the picture above and it gives that error..
