Editor thumbnails, sounds, and opening a door

[Damascus Rose]

I have 3 problems.

/////solved

No thumbnails are showing up for static objects or entities in my level editor.

/////////////////////

Sometimes sounds I play from script with the PlaySoundAtEntity() don't seem to play when others do, what is the cause of this?

///////////////////// solved

And I'm trying to get this swing door to open through script, and I've tried a few things, none of them work. I opened up the script from the Rainy Hall and copied it for my own door, but it has no effect. I also tried PropImpulses and Forces and still it does nothing. Right now all I have is

SetSwingDoorDisableAutoClose("nightmare_door", true);
SetSwingDoorClosed("nightmare_door", false, false);


If anyone could help me with any of these issues, that would be much appreciated.
