My test timer just wont start

Hi there - I'm hoping someone has come up against this in the past and knows how to fix it.I'm using Lectora 2007 SP1 and I've created a test with a timer (set to 60 minutes). The idea is that the test will automatically grade when the timer runs down to 0. Works fine in preview mode - but for some reason when I publish to HTML or SCORM, the timer just won't start counting down. Stays stuck on 0:59 59.The test I've created is reasonably customised in the sense that I've created my own buttons and feedback pages, and I've added some textboxes, actions and buttons at the test level that display prompts when you forget to answer a question or when you are ready to submit your responses. The test is also randomised, picking 5 questions form a pool of 10.I've tried shifting the timer box (automatically created by Lectora) around the tree (at the test level) thinking that some other actions might have been messing with it but no dice.Does anyone have any suggestions? I'm stumped.Thanks!
