Crashing -Macro page designer

Hi,
Been using the Macro Page Designer pretty regularly for the past few months.
Yesterday I installed the 6.2 update and have had three crashes in a couple of hours.

Building a page, dragging something on to the page and it crashes. also lost the Macro page I was working on.


Found this in the crashlog if it helps.
