Ok, I opened the file and did what I normally do and it was fine. You have to select the bitmap in the gallery and click 'background' (see the pic attached)

To Repeat:

Create your thin rectangles (which you have done correctly)
Then move this to the grey area
Select all the rectangles and right click and select 'Create Bitmap Copy'
Delete the bitmap copy
Go to the Bitmap Gallery and select the bitmap
With the bitmap selected click on Background (see attached pic)
