1. Sometimes renaming a group or object fails.

Steps:

- Right click to rename object or group in the tree.
- Wrong object name appears in the box, or blank

2. Move to tail sometimes fails

Steps:

- Right click move to tail
- Wrong object moved or no action

Both issues are fixed by restarting AC3D.

Better hide/unhide functions would be appreciated.
