Craig,

There's a bug in earlier releases of VFP where calling PEMSTATUS() more than once inside a single VFP command could increase the internal object reference counts and cause the objects to not release. ObjRef can not find these kinds of problems. The workaround is to split the calls:

ll1 = pemstatus()
ll2 = pemstatus()

if ( ll1 and ll2 )
   ...

instead of

if ( pemstatus() and pemstatus() )
   ...
