It is normal in any language (Gambas, VB, even C or C++) :

Event loop --> large proccess --> next event loop

   (CPU 0%)       (CPU 100%)        (CPU 0%)

You can "emulate" this effect using Visual Basic:


Public sub Do_Anything()

	Do While (True)
	Loop
End Sub

If you compile and execute this code using VB, you can
see a 100% of CPU usage, even, in some cases, other
tasks that needs to scan some resources like RS-232,
can fail due to this silly program.

 The first solution (in VB) seems to be:

Public sub Do_Anythig()
	
	Do While (True)
		DoEvents	
	Loop

End Sub

 But it really does not work!

 The solution in use is:

Public sub Do_Anythig()
	
	Do While (True)
		Sleep(1)  ' Calling to API
		DoEvents	
	Loop

End Sub 


In Gambas you can use a similar way : use Wait(1) which sleeps
proccess for a milisecond, so CPU usage will be near of zero!

This problem is matter of Operating System, not Gambas...
