1211: overlay manager stack overflow
------------------------------------------------------------------------------

 The Blinker overlay manager maintains a reload stack used in the management
 of dynamic overlays, and this stack has overflowed. The most common cause of
 this error is uncontrolled or unintentional recursion within an overlaid
 procedure or function, where a particular procedure or function is calling
 itself repeatedly.

 Please increase your BLINKER PROCEDURE DEPTH when it is low, and check your
 code for unintentional recursion.
