Compatibility mode fixes the editing issue for me, but I just wanted to check that someone else was having the same problem.
I'm a bit afraid of installing a new driver too!
Yea, if you only knew what I went through to just get x64 to install... The regular ISO file has a bug in it, that gave me this error when I booted off the dvd to install:
1.
2.
Select cd-rom boot type:
<end>
So I installed 32-bit, and followed
these instructions to get a working x64 disc. I had to copy the buggy x64 disc onto Windows, rebuild the ISO, and copy the fixed ISO file onto my dad's NTFS external HDD and burn another disc in OS X, using Disk Utility. And reinstall. After going through all that, I'm wary of screwing up my pristine, perfecting working (audio, bluetooth, all working, etc) Windows 7 installation.
