G'day,
First may I say welcome to the discussion groups.
Second may i say may you please give more details of your problem not just in the subject line.
Now, I also came accross this problem once before, it happened when I selected all objects and modified the dynamic column on the Mtext back to No Column. For some reason the mtext has a fit and makes the height massive hence blocks out the model space and you can not see your cursor.
So you may want to select all ctl+A and go to the properties menu and select mtext, and make the height zero (0).
Hope this helps.
Jason
