I=E2=80=99ve definitely seen the type of behaviour you=E2=80=99re =
seeing, when projects are very large with lots of keyframes.  It=E2=80=99s=
 happened to me on a few occasions when I=E2=80=99m importing .ma files =
and every frame has a keyframe for every property.  If you=E2=80=99re =
tracking in AE you might not have this problem.  I was generally able to =
get around it by deleting all unnecessary keyframes from the imports - =
most of the time there were keyframes on every frame for properties that =
didn=E2=80=99t animate.  This would generally make the projects smaller =
and faster to work with too.  There=E2=80=99s at least one script around =
which will clean up unnecessary keys - might be worth checking =
aescripts.

also an issue I=E2=80=99ve not had before.
