Mr. Hpasp,
Firstly, sorry for not being able to give you the translation I had promised, especially because I have offered myself to do it and haven't given you feedbacks so far. It's halfway and I believe I can finish it this month's vacation.

But I'm having a problem with your software's latest version. Even with the DEM off I have a huge frame-drop when I go to the Z-screen, both on the SA-2F and SA-2E (I haven't tried any of the others so far). I didn't had a similar problem with any of the previous versions of your sim.

Any ideas about what could be the problem? Thank you
