Weird ship behaviour in star systems

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Go to Celaeno IV in early October 2165.
2. Move the ship away from the planet directly "east" and let go of the 
thruster key, let the ship drift out of planet's partial orbit view.
3. Once screen zooms out, push the thruster gently once and let the ship drift.

What is the expected output? What do you see instead?

The star system view should zoom out and the ship should be moving away from 
the planet. Instead, the ship somehow re-enters planet view. It has happened in 
a few systems where the map zooms out almost as soon as the ship leaves the 
planet view slowly. 

[I'm going to bet this has something to do with planetary motion. When the 
planet is too close to the "zoom out" point, the ship probably "switches sides" 
or thinks it has just arrived at the planet when it as only just left. When it 
re-enters planet view, it's on the opposite side from its exit point.]

What version of the product are you using? On what operating system?

Release 0.2.1 on 640x480 in Windows 7.

Please provide any additional information below.

I've seen it happen in at least four systems. At first I thought I was crazy 
but it seems to happen every time the zoom-out happens at the same time as the 
ship leaves the planet view. I'm systematically cataloguing all planets with 
good resources so I've done a hardy bit of exploration here... may I say: You 
guys have been far more generous than the gods with the resources. Next time I 
need something, I'mma pray to Cedric.

This might be the planet motion. I'm on Betelgeuse at the moment and left a 
planet orbit to chase down a ship. I encountered them immediately leaving the 
planet-zoom, but then when I accelerated, I wound up back in the planet orbit 
screen again despite not turning.
