Stacks not ordering properly

I am trying to create a new “title” for a stack by:

  • Creating a new note above an existing stack
  • Selecting this new note
  • Selecting the items in the existing stack
  • Pressing the “Stack” keyboard shortcut.

The Scapple User Manual says, “Select the notes you wish to arrange into a stack. The first note you select will not move, and subsequent notes will be placed under the first note in order of distance from the first selected note.”

But the notes from the existing stack often switch their order. For example, instead of 1, 2, 3, 4, 5, down the page, I might get 1, 3, 2, 4, 5.

Sometimes if I select the two lowest notes and hit “Stack”, and then gradually add the next higher notes in the same way, one at a time (that is, select the new note, select the rest of the notes, hit “Stack”), it works great. But other times the notes still switch their order.

For example, I could select 4 and 5, then hit "Stack. Then select 3, then 4, then 5 and hit “Stack,” and so on. This workaround often, but not always, avoids a problem I might have if I tried to select the entire list and hit “Stack.”

Is there a better workaround for this?
