Remove Save Files dialog in FM12

Hello.

We have FrameMaker plugin system, which manages our own saving of FrameMaker files.

It works in FrameMaker 10. But now in FM12 this dialog appears:

And we need to disable this dialog and continue with close of FrameMaker.

I have tried to use  FA_Note_Dialog and return CancelOperation, but then the close event chain of FrameMaker is not continuing.

Basicaly we need to have Close of FrameMaker event chain same as in FM10.

Is it possible to do this?
