I already sent this message to softs4humans, but I'm posting here too,
maybe someone has an idea.

FM8 crashes if I try to print a layout with a calculated field that
calls a script (for simulating an "on enter layout" event). FM7 didn't
have this problem. It happens with both EventScript 1.0 and 1.1.
Do you have any idea how to fix this?
If necessary, I can give you an exmaple database that reproduces this
problem.

Also, the same thing happens when using the FMExample plugin that comes
with FMD7 (it includes a function called XMpl_StartScript)

I think I found an acceptable workaround: I set that calculated field
as non-printing (it was not visible anyway) and now I can print.
