Well, that's good to hear.

Excellent, thanks for sharing this tool!

Very cool, this tool rocks.

Well, everybody has different situations. But that's what I would do
if I were them, as it's kind of uncool to break other apps. Of
course, there could be additional ways for gtk-sharp or Tomboy to
protect themselves from this. I don't fully understand the
implications of this bug suggesting that gtk-sharp use
SetDllDirectory, but it could be a step in the right direction:
Thanks for digging into this, James. It's good to know that Tomboy
can still break in this situation. I'll try to work with the
gtk-sharp windows installer guys to figure out what to do.
