I never saw such bug and I have no idea what can produce it. Maybe it's related to the other problem you have in the other thread?

But you may try an (ugly) workaround like this:

lRet = .NULL.
do while IsNull(lRet)
   lRet = seek(cSeek, 'MyTable', 'MyTag')
enddo

Assuming that the DO WHILE will not be infinite :), this should "solve" the problem. At least, the program will work until you find the real cause.
