iMovie: Unresponsive, can't see playhead, no scrollbar

[aaquib]

Until this morning, iMovie on my MBP was working perfectly fine, but now I don't know what has caused it to be this unusable. On the top left where all my selected clips are supposed to be I don't see a scroll bar to go down. In addition, everything is extremely slow and unresponsive.

Is there something wrong? Activity Monitor shows iMovie using nearly 900MB of RAM and I have no idea why it's so high.

Hi Aaquib,

Did you find out what caused this or get a resolution. The same thing has just happened to me today. Very frustrating as it's now unusable.

Thanks
