Hi,
I'm using InfoQube 0.9.113 (2019-05-22).
As shown in this screen-recording (http://bit.ly/2wsgnMF) and in the snapshot below, if you access an item set to shown MHT or PDF content on doc pane, unnecessary/extra borders are appearing.
Examining further, I realized the borders are from a previously HTML item content that remains visible, overlapping the MHT or PDF shown on doc pane.
Thank you!
Carlos
