Horizontal Preview Not Showing When Switcing From Vertical

Good morning,


  • Windows 10
  • Edge


  • Login in to RMM7 Beta
  • Select a message which shows a Vertical Preview to the right.
  • Click to select Horizontal Preview > no Preview shown
  • Problem seems to occur due to horizontal bar being right at the bottom, if dragged up a Preview is visible.
  • After setting horizontal bar should I switch to Vertical Again and back again the problem will re-occur.
  • Selecting a different message after selecting Horizontal Preview doesn’t result in a Preview showing.

It’s like Horizontal Preview position is not stored when using Edge. FYI Indexing was not active…

I tested with Firefox 61xx and it seems OK with the above and Preview is not lost.
