Dialogs module

though it works, I get errors in the server log when using several calls to the mod_dialog without closing the previous one.
ie, everytime a dialog is returning a value, it is marked for cleaning and there is an attempt to remove it from history which fails as the form is still busy if you call another dialog. it will be deleted later on as every attempt is trying to clean the whole bluePritnStack. Could it be modified in order that the removal attempt is done only if the form is not in use? I have not found how to achieve this...
