Attempting to delete frames from a project causes the CPU usage to spike over 100%.
Causing the application to hang, and be completely unresponsive. This condition occurs
for 30+ minutes until being killed manually through terminal.

steps to reproduce:
open project
click project on timeline
click project again
click on frame
drag to select frames to delete
right click select "delete range"
Select radio button that says "Delete frames"
select ok
wait (for ever)
nothing happens only spinning ball.

Expected result:
the frames are deleted almost instantly

additional info:
CTA3 updated to 3.01
~/lib/pref/CTA3.plist deleted
reregistered license
tried on CTA2 and worked instantly as expected
