@Biellonzo Fixed. Can download here https://drive.google.com/file/d/0B-sqEGE7Jbc7Xzh6YnJuRVI5MlU/view?usp=sharing
The issue was with window.outerWidth == 0 in BAS, and some startnge code window.outerWidth || window.innerWidth from recaptcha service. If window.outerWidth == 0, so function, which calculates screen width, returned window.innerWidth which was always 304px, because code executed in captcha frame.
Why does it take long time to start a compiled script?
It takes too long only on first run, because installer have to download correct BAS version from server on first run. Correct version and correct architecture(x86/x64)
I guess its to download the appslocal folder.
Does it download this folder for all the compiled scripts?
It downloads engine folder and unzips it to appslocal, if necessary engine version already in engine folder, than downloader just unzips it.
