Hi Luiz I'm not sure if this can be done or not... (my *guess* is that it can't be done but then again I'm not sure). Anyway, this is something that happens with 99.9% of the software out there... If you remove the CD even though it is still needed you will get the blue screen (BSOD). That is simply something that the user should be aware of in my opinion. If your software was the only one doing that then that would be a problem but it is more of a structural problem IMO. Cheers.

I have a project that runs on CD-ROM. Sometimes it loads some files that I tell the projector to load, when I do that - I check if the volume (CD-Drive) is mounted or not - to avoid problems. Sometimes the movie can't fit entirely on the RAM so the projector loads the movie in parts but lets suppose that the user removes the CD-ROM from the drive.... He(or she) gets an uggly blue screen warning that sometimes crashes everything and requires a reboot. How can I get a message in lingo everytime director needs to access the disk, so I can display a 'pretty' alert message avoiding the user to get those uggly Blue-screen message on windows?
