I'd like to know if anyone else has experienced iMovie effects sending the selected frame into a "Blue Spasm"? For some unknown reason when applying the 'lightning bolt effect' we now have a situation where the selected frame takes on a pale blue wash over the whole image . We're using iMovie V4.0.1 in OSX 10.4.3 Any one got any ideas where to start to sort this out quickly. This is a new issue, never seen it before. Only recently done OSX updates, no previous problems with this version and no idea why it has started!!!!!
