Thanks for the feed back. I didn't think to check the browser console.
For the todo entry when I try to check or uncheck a box I get the following in Chrome:
Uncaught ReferenceError: addInitEvent is not defined js.php?tseed=1376720394:2
Tablesearchjs gives the following:
Uncaught ReferenceError: searchtable is not defined doku.php?id=tasks-sandbox:todo-test2:10
Updating Tablesearchjs does not fix the issue. Same for Todo. Seems like this should be a browser issue? I've check it in Safari, Chrome, and Firebox on MacOS X, all with the same results. I'll check it on windows later today.
