I have unexpected behavior with the keyframe controller - how do I keep the keyframe controller's timeline from zooming out completely every time click on a keyframe?

I'm using keyframes to control some video plugins (levels and color corrector mostly). I started out using them at the track level, but did not like having to "reset" them for all the generated media I have inserted along the timeline, so I switched to using video event FX. I have some unexpected behavior with the keyframe controller. Some of the keyframes are very close to one another - some are 4 frames apart.

With the controller timeline zoomed way in, I can click on any visible keyframe and modify its parameters. If I click on a keyframe for the non-active FX then the time line zooms completely out so the whole event is shown. It also zooms out if I click on the FX name off to the left of the keyframe controller.

Is it supposed to work this way? Is there a way to make it stop doing this?
Thx, Marc
