You can prevent changes to object properties by locking the objects
in either the General Tab of Object Properties dialog or in the
General palette. Locked objects cannot be changed in any way, even if
they are part of a group, which is being modified. The object is
unlocked when you release the "lock" option. Locking and
unlocking are realized with the help of the
button. The presentation pictured above is typical for unlocked objects.
To lock an object:
* Working with a certain object and being either in the General Tab of Object Properties dialog or in the General palette, click the Lock/Unlock button. The application locks the current object.
To unlock a locked object:
