Gregoire,
The default sleep policy for CVI applications was changed in CVI 5.0.1. In
order to make CVI apps
behave better in a multitasking environment, the sleep policy was changed
from VAL_SLEEP_NONE to VAL_SLEEP_MORE.
You should read the SetSleepPolicy function panel help, and then decide on
which of the three values suits you best.
