Dear Ross,

Since my nuc.pdb file cannot be opened by x-win, I have downloaded the nuc.pdb
file and nuc_ter.pdb from the tutoral website. The result is same. I edit DA5,
x-win32 also do nothing on the screen. Edit LYS gives me same result with
aboves.
Before amber8 was installed, we have downloaded all of bug fix files from
amber's website.

Here is the pdb file and leap test .log file.

Thanks!

Xiaowen
