Here is a workaround I found meanwhile for the ask/answer dialogs
remaining on top of the screen with longer repeat loops:
As changes in objects under the area of the modal dialog wipe out the
respective part of the dialog, set the rectangle of a field or button
(transparent without borders and name) to the rect of the modal dialog.
It is necessary to change the rect of the "covering" object afterwards
(or before), because when it remains unchanged next time the modal
dialog stays on top as before. *Changing* the part of the screen where
the dialog is displayed is the essential part of the workaround.
Here a sample script:
"on mouseUp
answer "Change borderwidth and bordercolors?" with "Yes" or "No"
put the rect of stack "answer dialog" into d_rect
set the rect of btn "cover" to d_rect
show btn "cover"
hide btn "cover"
set the rect of btn "cover" to 3,3,10,10
send "mouseup" to btn "change borders"
end mouseup"
