I've found a bug using Toodledo with Chrome browser.
When I click on "Due: no date" field, to set up due options "Due Date and Time" window appears and I can set Date and Time, but I can't chose options like "due on", "due by", "due after", etc. When I click this field the "Due Date and Time" window closes and by default it remains "due by" option.
I can change this options using firefox, but it doesn't work in Chrome.
I use Google Chrome 5.0.375.99 beta on Ubuntu Linux.
