This is considered invalid code. It will cause the app to freeze until it is killed.

Add Sleep(0) if you want to create such loop.

Without any error
'Program terminated (StartMessageLoop was not called).' on log windows

 

[DonManfred]

Program terminated (StartMessageLoop was not called).' on log windows

Add StartMessageLoop before the loop then
