Some users have noticed that when you open the Animation Editor for the very first time, and click the Edit menu, it takes a little while for the Edit menu to appear.

That’s because the Animation Editor loads plugins when you click the Edit menu (for the very first time).

What happens is that when you open the Edit menu for the very first time, the Animation Editor scans the custom command maps looking for any commands in the siFcurve command category (the AE uses a custom command instead of menu anchor points–see the FCurveEditor object in the SDK docs for more information).

This scan causes the plugins to be reloaded, but this happens only once per Softimage session.
