Thanks for the info. I had the IRQ sharing problem on my old computer. Since I purchased my new computer, I made sure to install the sound and video card on their own IQR, so I'm sure mine is not shared.

The popping noise reported with the Audigy card happens to a variety of programs. It seems unrelated to this paticular problem since it actually cuts out and only happens with FS one.

Everybodies computer is different and it probably impossible for programmers to test all the variations for a new program. I think it is acceptable for a new program to have bugs. I am just hoping a patch comes out to address this.
