"......but it is getting very frustrating to work with screen4........."Join the club. How many users have said the same thing.
Scream4 is certainly a bit idiosyncratic but it will work once you get used to it.
The best thing is to use a larger monitor so that no scroll bars are needed. That will save 90% of the frustrations.
Some have worked around that by using a mouse with no scroll wheel.
Sounds like you should watch the tutorial video too. It is basic but will show you how to select buttons without the screen changing pages.
There was a program being developed called Jetcam, but the developer has, if not dropped it, at least set it aside for now.
And then there is the option of developing flash screens but I have no experience with that. Look for posts by "zealous"
