Im abashed whats is happen with fullscreen window when i make test run?
That problem shows after window reinstal and program installing from new!
Before this if i write fullscreen = 1 then test run shows in full screen but now no!

I want how can fix that!

Just read the manual.

That isnt anything new! Im always writing fullscreen = 1; and video_mode = 8; But how i say after program reinstal that dont works in test window but ufter publishing works like full and in real resolution!

Take a look at the command line and delete "-wnd".

I think what JCL meant you to notice was that you have to set video_screen to 1 in your main script.

In this all most stupid thing when that dont work anymore - that video_screen =1 and 0 is the same effect (in test mode)! But before that programm reinstalling all works great! Im all time trying to say that - when im doing all that what before! But now dont work!
Im not so stupid!

I think its 1 and 2 not 0 and 1...

did you try to use the function video_switch or did you just set the variables?

Yeah. I'm truly sorry if you think we're acting like you're stupid, but we we just need more details about exactly what you're doing. Did you define video_screen like this:

video_screen = 1;

OR like this (the correct way)?:

// outside of any functions!! at the beginning of the script
var video_screen = 1;

For checking this, use TAB in the engine and type video_switch(0,0,1);.

with video_switch all works fine!
Bat some time ago this be worked without any video_switch too!
