Platform Movement Object out of screen

Hi,

Might be a noob question again. But I have a scrolling level. And got everythnig setup like it should be for the PMO. And it works great it collides with the backdrops like it should. But as soon as the level starts scrolling and the pmo is outside the frame space it does not collide with the backdrops anymore and fall out of the window. What do I need to do to fix this?

Thanks,
Maarten

Go to the frame properties, and tick "handle collisions outside of window".
