Lensflare Keyframe Time lost when saved

Hi All,

I have recently got Vegas 11 (build 510) and am having a problem with Keyframes on lens flares. Does anyone know how to fix this or Has anyone else had the same problem?

What I am trying to do:
-----------------------
Have the lens flare travel across the screen under the text.

What I have done:
-----------------
I have 1 video track with simple text
I have a 2nd video track with a simple colour gradient and a lens flare.
I animate the light position with two key frames. The first I set at the start (0:00) with the light at the left. The second I set at about 4 seconds (4:04) with the light at the right.
When I play this it works exactly right.

The Problem:
------------

When I save and then re-open my project the animation has become faster. This is because the second keyframe has moved to about one second (1:18). I also found that if I save and re-open it again it moves again (0:18) and the fourth time to (0:07).

This does not happen with other animations I have tried on other effects.


Does anyone have any ideas or suggestions?


Thanks in advance
