I've been having intermittent exceptions in js32.dll 1.5 rc5 (thread-safe) -
I'll post about those next.

Anyway, so I've been trying to upgrade to 1.5 rc5a with no success. I,
almost immediately, get this assertion/exception when running one of my
bigger application scripts (an IRC server):

The filename string passed to js_MarkScriptFilename() is an empty string
(""), not sure if that's significant or not.

This same script runs almost perfectly using js32.dll 1.5 rc5.

Thanks for any pointers,
