Upon selection of image IMCE window should close

This is how to reproduce this behaviour

You open up the IMCE browser and select an image
the focus goes to the TinyMCE's "edit/add image" inline window
but the IMCE browser stays open

Upon the insertion of a new image another IMCE window opens up
(total two IMCE windows) and so on

Anybody else see this ??

I am using IMCE with TinyMCE latest and Firefox latest build
