I seem to have found a solution to the problem that's so confounded me for the last few weeks.
By composing in Wordpad and saving as a plaintext document, then cutting, pasting, and making the necessary adjustments within Typepad's "compose" form, I've thus far been able to avoid weeping, wailing, gnashing of teeth, exessive use of potty language, and the urge to do icky, heathenish things to my "tormenters," if you will.
Just thought I'd pass that along.
