MultiView plugin Viewer bug?

I've gone through all the forum entries I could find (searching multiview, viewer, plugin, etc.) and haven't seen this problem posted yet, so here goes. If I've overlooked something, please excuse me.

I've tried configuring the multiview plugin to use the Stellant filters provided with X1 (as per suggestions in other forum threads). To my great distress, they simply refused to work. Finally, I discovered that I can activate as many plugins as I like (e.g. source text), as long as I have the "Configure" window for the multiview plugin open, they all work. As soon as I close the "Configure" window, the multiview plugin ceases functioning, regardless of whether I have any other plugins active or not.

Is there anything I can do about this?

Grateful for any help.
