Hi Khaled.. apparently this will solve my problem, but the people that turn it off doesn't have anymore the flash on query.. that's not good to me.. because the query windows is very different from the dcc window smirk
The simpliest and correct method to me is to make the "button" of the dcc remember the settings of the flash (it has only to save it in the ini!), and make it accessible via script in a simple command like:
flashing windowtype windowname on|off

Bye, Luca
