Being the razor's edge kinda person that I am, I have downloaded and installed this already. Many fixes and more stability updates.
In my initial test on a drawing that regularly crashed C3D2008sp1 (as of last night) I was able to do in about 3 minutes what I could not accomplish yesterday. Definitely a good start!
Supposedly the MOO's have been fixed, but haven't yet tested this.
There have been a few reports of the install not working. However, both the C3D & LDT SP2's installed on my machine without a hitch. Although the LDT SP wanted the LDT install DVD while the C3D SP did not.
