[pocxxl] Game hangs in charter window when sorting

[shahmatt]

Bug is reproducible on latest pocxxl:

when ship menu opens:
1. select "CHARTER"
2. sort by "result/unit"
3. double click on cargo
4. select "calculate route/ETA"
5. select "remove freight"
6. sort by "result/unit" again

and game hangs...

EDIT: It not happens every time, but it happens.

I will check it and fix for the next update (now in sight) -- looks liek a bug in the list system.
