Thanks for the comments, guys - sorry I didn't reply to any of them sooner.
Unfortunately, I don't have any plans to fix remaining bugs in this plugin - my familiarity with the code has dwindled over time, reducing my ability to identify problems. This, combined with my full-time work and school schedules - which leave me little time for my current projects - means I'll be dropping support indefinitely.
However, I would like to say that I've just finished tinkering around with the C2 plugin SDK a little bit and I'm starting to get a grasp of what's going on in that regard. With any luck, you'll see something on that front in a few weeks time, although I make no promises.
In the event that I do release a C2 version of this plugin, updates will likely be sporadic and I might start accepting donations as a way to offset the time invested. Life is a demanding mistress and I am submissive to its will.
Be sure to keep an eye out for any updates - I'll let you guys know as soon as I have more to report.
Once again, thanks for all of the downloads and comments for this plugin - I see it as my crowning achievement in this community and the support is much appreciated. <img src="smileys/smiley1.gif" border="0" align="middle" />
