Seemed to have narrowed down the problem of pdftex not stopping upon exit of Lyx. I was using the Koma-script 2 letter template, and I added a maths \rightarrow symbol in the text of the letter. This problem would then appear. Don't know why. Take it out and the pdftex process stops and starts correctly with Lyx.
