Ok i've got this problem sometimes when i take my .EPS and i want to convert it to PDF files with Adobe Distiller. I drag my .eps in Distiller and then, not all the times, and not with all .EPS, but it tell me that the file is being used by another program.

The thing that is weird with that is that, even if i close my computer and try on another one, it tell me the same thing again. So i have to make copies on the files to finally be able to convert it. Sometimes it work, sometimes not.

Someone have an idea what may cause it ?

Thanx for your help
