> So one RETALL is not enough to get a normal return , but if I give four RETALLs then there is enough of an extra "push" to give a normal return ;-) I first thought this was just a timing problem, and that the pointer cleanup wasn't complete at the time of the first RETALL, but it was complete by the time of the fourth RETALL. But the errors always appear in the same pattern as above, requiring 4 RETALLs no matter how much time I give. Any suggestions as to what is happening? Thanks, --Wayne
