I have had similar results with the Adobe product on WIN95.

Perhaps mine will help shed light on what's going on. I can send out to the PDF files, several in a row with no noticable problems... at least for two or three, with no pauses, however I have had later reports overwriting earlier ones if I didn't put some sort of delay in to let the first report complete.

I can also run this same program twice in succession with no negative effects, but when I try to load the program to print the report set the third time, my hour glass keeps turning, but everything else is dead... no error messages etc.

It's almost like some memory has not been released when the PDF translation is finished and Fox insists on writing to a particular address.

Anyone else have any thoughts?
