Hi Mark:  I run into the problem quite often when using the editor but 
it has been hard to reproduce it reliably.  This seems to do it.

Radio recording with cutpoints esablished near the start and end.
Start playback, hit > several times and < a few times, then E repeatedly 
and maybe for slightly longer than would be normal in keyboard 
operation.  The first E enters the editor and later ones toggle playback.

By 'flash from  cache' I just meant that playback usually starts with 
very quick display of some previously displayed frame.  Perhaps it could 
be from the deinterlacer.  It's no problem but suggests, like the gently 
pulsating cursor, that something isn't quite right.  This is, of course, 
all on an old machine without advanced video hardware. I don't use it 
for 1080 or h264 content.

Thanks,

John
