Oh boy, is this late! ^^;
This is a minor build (mainly a backend rework, not much user visible stuff.) Basically, the UI no longer locks up when a comic is loading.
If you encounter any bugs, submit them to http://www.markkb.com/stuff/bugs/ and I’ll see what I can do about them.
Oh, the comic in the screenshot is the awesome El Goonish Shive. Check it out, won’t you?
