Nadya,

A search of the MS knowledgebase showed that "invalid file descriptor" errors show up in a couple of different curcumstances, but there was no mention of NewObject(). A search of the UT archives revealed the following:

Update: Microsoft tech support has agreed that this as a VFP6.0 bug, which is "likely to be fixed in the next Service Pack or Version"...

We found a work-around, however. Before including a classlib or application name in the newobject() function, make sure it is NOT included in SET('CLASSLIB').

IF 'mylib' $ LOWER(SET('CLASSLIB'))
llObj = NEWOBJ("myclass")
ELSE
llObj = NEWOBJ("myclass", "mylib", "myapp.exe")
ENDIF
