We noticed this as well.

This is because ultraedit effectively moves the original file to the bak
file first and then create a NEW file (with indeed the rights of the current
user). Because of the group writable bit this is completely legal.

The only thing you can do is remove the group writable bit, but then users
in the same group can not edit each other files. I consider this more a bug
in UltraEdit (it should create a new bak file iso moving the original file)

kind regards

Willem Jaap
