I agree that this should be a show stopper, so that the patch from 
Dennis (or something to accomplish the same effect, and retain the 
current Blowfish method as the default) should be integrated.

Given that, there are two more options to consider:

3. User change to config file, to use the new option.

I have suggested a writeup on this, but such instructions are much 
better aimed at the (few?) users who want the "latest and greatest" 
security option, and will do a little work to get it. (Does anybody know 
what that file name is? Given that, I volunteer to update the Release 

4. Macro to toggle the settings.

This could be distributed in a BASIC library (new or existing); no 
extension necessary. User instructions to find and run the macro are 
simple. I may be able to write this; preliminary investigation is 
promising but not certain. I volunteer to try. There are several real 
experts on this list, whom I might ask for help.
