Try moving your cursor to the edge of the frame. You should see the cursor change to a double headed arrow <-->.
Right click and hold on the arrow and stretch out the frames to the size you want - top and bottom.
Close the window, and when you reopen them they should remain at the size you've set.
Don't close it with the X when you do this. Right-click and select Close
