In some situations the Print object start holding data, then after some other "unrelated" event, it releases all data at once.
For example, if I reload the project all works normally.
If while holding I crete a watch point anywhere in the project, then when debug enabled, the next data that arrives to Print object releases all previous data to the Max window.
When this happens it affects all present Print objects.
Is this a known bug, or I'm doing something wrong?
