There are some updates to the regular expression engine going on. There is another update at http://www.nextup.com/files/ta3.exe. Would you mind giving this one a try? Let me know if this does not solve the problem.
Would you please send me the dictionary entries that seem to be causing the problems? If it takes too long to isolate specific entries, just send entire dictionary(s) and I'll sort it out. Please mail this to me at firstname.lastname@example.org
