Asset editor size / using my model in RW2

[DOM107]

Hello,

Thanks in advance for your replies.

1) I've set 1920 x 1080 as screen resolution in the RW2 settings tab: the game resolution is OK but the asset editor is very small.
How to change the size of the asset editor window?

2) In the world editor, using the Object Filter menu + menu on the right hand side of the screen I can select my train name.
But when I click on the train name and then on the scene, nothing is displayed.
If I select a train provided in the software, it is displayed on the scene.
