Accidentally moving objects

There is no real way to prevent this other than having a fairly stead hand. If the mouse moves when the mouse button is held in, the object will move. If this is happening a lot and you are definitely not moving the mouse, then this is a problem.

PS I suppose one could constrain movement on the X, Y and Z axes. But that would be really annoying to do on a regular basis.

I have 3DC 5.0 Pro. I found out that I can accidentally move objects while I click on them to select them for operations such as merging objects together. How can I prevent this? Jeffrey.
