Diagnosis
When moving or copying a block consisting of one or more elements, thetarget block must be the same size as the selected block and empty.
If the block contains elements with the attribute "Permanently visiblepossible entries pushbutton", there must be enough space in the targetarea to display the possible entries icon. At the same time, you shouldensure that there is sufficient space for the possible entries icons ofother elements.
In this case, there is not enough space, or the right or lower edge hasbeen exceeded.

Procedure
Place the cursor so that the target position is blank. If this is notpossible, you can cut the selected block and paste it into anotherscreen. You can leave the select mode with F3, even if no block wasmoved or copied.
