Minor camera bug in 1.5.1 and 1.6.0 when right-clicking

[TranslightDefender]

Hi

This minor bug wasn't present in version 1.4.1.

I start 1.5.1
After arriving at Earth, I right-click on another object, say the Moon or a distant star.
In the popup menu, I click on the object's name.
The camera instantly jerks when it centers on the object.
If I click on the name quickly after opening the menu, the camera partly jerks then turns to center on the object

Doing these same steps in 1.6.0 give the same result.

When I do it in 1.4.1, the camera smoothly turns to center on the object, regardless of how long the popup menu has been open.

It is not effected by the presence/absence of addons, and running it in XP compatibility mode has no effect.

I am currently running Windows 7. Previously I had XP (with an earlier Nvidia card, slower dual-core CPU, and different hard drive) and these same versions of Celestia with the same camera behavior.
