My first point of call would be the app's memory allocation. I've seen this
error in applets that otherwise run fine in an editor; I've wasted hours
trying to track down problems, only to find them go away when I increased
the applet's memory partition.

There's no such limit. The 32K business only comes into play if you want to
do comparisons, or get word x of aLongString.

Repeat: there is no 32K limit. I've had variables holding megabytes of text.

Sounds like needless caution to me.

Try the applet's memory first. And check that the user had enough free
memory for the applet in the first palce.
