Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.

Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|

I do not know if I fully understand your issue, but let me suggest a couple of things. 1) If you just want to count the passage of electrons through the boundary of xenon and copper, you may do it in your UserSteppiingAction. Check the volumes of PreStep and PostStep to identify the volume crossing. 2) You may also use the flux scorers provided to count the particle flux. You may want to use the particle filter to score just electrons. Please visit to the recent Geant4 tutorials, for example http://geant4.slac.stanford.edu/SLACTutorial07/ to see the scoring lecture notes. Hope this helps.
