QB64-PE v4.2.0 is now available

[a740g]

On first launch, when you hit F5, QB64-PE compiles several internal libraries required by your program. This only happens once per feature set. So, the delay you're seeing depends on what your code uses.

For instance:

• If you use SOUND, the audio libraries will be compiled.
  
• If you use _LOADIMAGE, the image libraries will be compiled.
  

Not all internal libraries are built on the first run - only the ones your code references. That's why the initial compile is slower, but subsequent runs are much faster.
