If you use the Clipping Path command on two objects (maybe more), and then lock the new object, it cannot be unlocked. I saw this in version 2, now in version 3. Is this a bug or is there some reason for this inconvenient feature?
have you paid attention to unlock first the layer were the clipping masks are on? I work in design 1 if the layer is locked were the clipping mask are on I first need to unlock the layer
