Eclipse Mod movement issue

[Strategia_In_Ultima]

For some reason, when I move a vehicle in the Eclipse Mod, it moves one sector, then the game "hangs" for like 20 seconds or so, before it moves another sector, at which point it hangs for 20 secs etc. When the game "hangs" I cannot do anything, it won't respond, when I move my cursor over a button it won't light up and no description will appear etc.



edit: Correction, make that 40 seconds when I'm in a system with another race's homeworld with an Escort in orbit.

Low tech start, turn 1, probe with 19(!) movement.
