[OpenMap Users] Problem with Limit Chart Selection for Rpf Maps

Hello All,
        I have a customer who is experiencing a problem with their CADRG
maps. I have been unable to duplicate the problem so I am passing it on
to the group here to see if anyone else has encountered a similar
situation. The following are the steps the customer used to cause the
problem:

1- Open RPM and select to an area that you have to adjacent scales of
CADRG (eg 50K and 100K).
2- Type 50K in the scale box, thus bringing the scale to 50K.
3- Open the layers tool, turn on the light bulb for CADRGs, and send
it to the top of the list. (Do NOT close the layers tool window.)
4- When the 50K scale maps appear in the viewer, click the palette
button between the light bulb and the CADRG name to open the properties
window.
5- Click the "limit chart selection" box - it will probably read
"null".
6- Now type 100K in the scale box - no map!

....and the stack trace

*** ERROR ***
