FrameMaker 10 Internal Error: 10024, 7687720, 7688010, 10076471 when using Spelling Checker

When using the Spelling Checker, a book crashes with a FrameMaker 10 Internal Error: 10024, 7687720, 7688010, 10076471

This is not book dependent. This error occurs with different books, none of which had problems or crashed until now.

I'm running Windows XP Prof.SP3

Any suggestions as how to fix this?
