This animation thing IS cool It took awhile to get it right but I just made a flashing text of my initials like a neon sign.
It seems or maybe supposed to be this way but if I select text then write something on the screen try to add the frames they are blank. If I write the text then select then add the frames it works, if I try to select the text then move it around the text in the right pane stays the same. It'll take me awhile but I'm gewtting the hang of this thang. Side note, the text font selecter stays the same on most fonts there are a few that do change in the font sample.
BTW-the animation .raw file you just posted do you just open and upload the file from the animater?
