CPO Get from Host problem

Does CPO limit the local working directory to one under "C:\WDT400"? In CPO,
I set the local working directory to a directory outside of "C:\WDT400" such
as "C:\My Source" and the get from host function would not work. I changed
the local working directory to a directory under the "C:\WDT400" such as
"C:\WDT400\My Source" and the get from host function started working again.

>From DOS I am able to execute the CODESRV GET command using the "C:\My
Source" after cutting and pasting the command from the confirmation prompt
in CPO and appending the member name to the end of it.

I'm running WDT/400 V5R1 SP3 under Win2K.

TIA,

Brian
