QB64pe 4.0 on Mac Troubles

[NakedApe]

If I type this into the IDE and hit F5, it creates a .command file and an exe called 'untitled' in the QB folder, but doesn't run.

Code: (Select All)

Cls

Print "Hello World!"

Sleep

System

If I save this as hello.bas and then reopen it, it still won't run, but makes a fresh exe each time. Da heck?
