Kris, Thanks for your quick response. We had a big holyday here in Spain since last friday(till yesteday) , that's why I didn´t made any comment before.
As I told in the last message I was using the Flash CS4 on a Mac to compile/run the projects. Maybe it is out-to-date, will check it at work. Also I made a try to run the same project on a PC computer at home and the blankscreen did not poped out. So hopefully it is all under control. If I have any news about that I'll comment under this post to keep all tracked out. :-)
