Possible masks tool bug?

[johnp]

I have created a somewhat complex mask.

I then do some other transformations, such as brightness curve, then I go back to modify the mask and it looks like it may be
re-calculating the mask steps twice...

I double click on the mask transform, and it looks like it is recalculating the previous mask - ie, I see the spinning wheel pop up and down, and it all takes a while. It then shows the initial 'masks' dialog box. I select to re-edit the mask I'm interested in , and it then appears to take a long time to re-calculate it before it actually opens the mask editing window.

The first delay seems odd since I have not yet seen the initial dialog box that allows re-editing an existing mask or editing a new mask.

Thoughts?
