After renaming your .scr file don't forget to copy it to c:\windows\system32
or it won't show up in the screen saver list Exclamation

That's what INSTALL does for you.

Thanks. 

I figured out the mouse problem... For a screensaver, we want it to quit if the user moves the mouse. 
However I was having a problem where it would quit immediately even if the mouse wasn't touched. 
What I found was, we need to save the initial mouse coordinates AFTER the SCREEN _NewImage. 
But also, we need to give it a couple seconds to initialize, so we put in a _Delay 2 for good measure.
Here is one of @bplus's cooler eye candy proggies, with the mouse check added, it makes a great screensaver:

Go back and check my example for you: https://qb64phoenix.com/forum/showthread.php?tid=3609&pid=33538#pid33538

Screen _NewImage(320, 240, 32)
_FullScreen
_Delay .5 'give the screen time to initialize fully so we can associate mouse input with it and such

RE: compiling QB64PE programs into Windows screensaver SCR files? - madscijr - 04-23-2025

Gotcha. I seem to remember _Delay .5 not being long enough but I can try it again. 
Thanks
