There is a limit to the amount of data that can be sent in Apple events.
The most common number stated is 32K minus some overhead, although I have
heard 64K on occasion. Here are some things you can try:

1) Install AppleScript. It supposedly works around this limit by patching
the Apple event manager. You don't actually have to use AS, just enjoy this
side effect of having it installed. Since you are using 7.1 you may have to
go through some gymnastics to get it since AS isn't distributed by itself.

2) Obtain the "Apple Event Manager" extension from one of Apple's ftp
sites. (Good luck, now that SU 2.0 has hit the net.) It is rumored to
contain the same fix as the AppleScript extension does.
