Wow! You found a serious problem... an 'runaway' loop caused by a *programming error* on my part!!! It's been fixed. Get the update (v1.2.2) here: http://www.TiddlyTools.com/#ListboxPlugin http://www.TiddlyTools.com/#ListboxPluginInfo Here's the details: When any tiddler is changed, config.macros.select.refresh() is invoked so that listbox contents can be kept in sync. This function contains a loop that starts with this code: for (var i=0; i<lists.length; i++) { ... which calls upon config.macros.select.render() to re-display each listbox whose 'listsrc' matches the title of the tiddler that was just changed. However, inside render(), there *was* this code: if (here) for (i=0; i<here.options.length; i++) { ... The problem: in the second piece of code, the loop index 'i', was not declared as a *local variable* (i.e. using the 'var' keyword). As a result, the loop within the render() function 'stomps on' the value of 'i' that is in use in the calling function, and that loop ends up re- rendering the same listbox over and over and over and over.... The fix was simply to change that second bit of code to: if (here) for (var i=0; i<here.options.length; i++) { ... The lesson for programmers: Make sure to always use 'var' to limit the scope of simple loop index variables to the current function only. enjoy, -e --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
