Comment 7 for bug 663815

I have this problem too. I have a fat32 and another vfat mount with .exe files and other executable files was trying to install under wine. I could install it fine under 10.04 and 9.10, but since installing 10.10, I can't install them from the usb anymore. I tried changing permissions but couldn't, the check appears for a second, then disappears again.
The same applies to CDs and DVDs with all kinds of executable files (.exe, .bat, shell scripts, txt, etc), and I can't change permissions neither from file properties nor using chmod 777. I actually can't seem to install anything at all unless it happens to be in my linux partition. The result being that every time I want to install a DVD, I'm having to copy 3-4 GB to a folder in my home folder, do a chmod 777 to it, install it and then delete it.
I'm going to remove 10.10 and going back to 10.04 because I've already wasted several hours over this :(
Is there anyway to revert nautilus back to the way it was before without reinstalling the whole OS?
