the cursor with a small cross with four arrows

I have Corel X5.  I have the standard cursor which an arrow pointing upward to the left.  When I select some things the cursor picks them and I can drag them and the cursor stays an arrow.

When I pick other things the cursor turns into a cross with four arrows and as i try to select and drag it turns into a small cross with small arrows but i can't select what i want.  What is happening?
