 :::::Well that was only a cosmetic issue, not a flaw in the regular expressions or anything serious (basically, a button was added to AWB in an area where (through a hack) I latch onto checkboxes. I've made it more robust by having the code check that each object in the loop actually is a checkbox before trying to use it like one. Really nothing to worry about. :::::WRT to testing the new novels plugin, a test of each parameter over a random sampling of 100 or so pages really ought to be enough. The plugin is built on the same base code as all the others, and that basic code is obviously sound given the absence of complaints! Worry ye not, in other words.
