This sounds like this bug https://quality.livecode.com/show_bug.cgi?id=23088,
which should be fixed in LC 9.6.6 RC-1 and newer.
If this is not the case for you, could you attach a sample stack and the
pdf to this report and reopen it? Or send it to me directly if they are
confidential. Also, it might be worth checking with the 32bit version of LC
