a memory backup, the receivin
g
unit’s available
memory is insufficient to receive all items in the sendin
g
unit’s memory. A messa
g
e indicates the number of bytes
the sendin
g
unit must delete to do the memory backup.
Delete items and try again.
MODE
You attempted to store to a window variable in another
g
raphin
g
mode or to perform an instruction while in the
wron
g
mode; for example,
DrawInv
in a

mode
other than
