Turn off automatic zooming when editing text in draftsight

Hi everyone. I have been using draftisght for about a year now and recently started having a problem with editing text boxes. When I double click on a textbox to edit the text draftisight auto zooms in on the textbox. Then when I click outside the textbox it auto zooms back out. It only happens on some text boxes and not all of them. Does anyone know how to turn this annoying feature off in draftisght? Thanks.
