All right Damien! The files i did send to you are LV 6.1 so that=92s a problem if you are using 5.0. But in words i did it like this. In the functions pallet i used Functions->Application control->Open VI Reference Functions->Application control->Property Node Functions->Application control->Close LV Object Reference
For the Property Node i used the attribute "Front Panel Window->Open" This is a Boolean and True means show front panel and False don't show. I'm quite shore this will work in LV 5 to. /Thomas
