Additional context

Demo wait for a value set in memory by AddIntServer() to sync with VBL. This value is not set so the demo looks freezed.
Prior to call AddIntServer the demo do a disable() and Forbid().
If I remove the disable() / enable() call the demo run.
It happens on other demos.
It looks like an issue with IDNestCnt but I might be wrong.
