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.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|

In your physics list you are using the 2BN generator for bremsstrahlung. This generator which offers a more detailed treatment of the angular distribution is about 40% slower (10-100 kev electron energy) than the original "modified Tsa"i generator, although at these energies and in soft tissues the probability of bremsstrahlung emission in not significant
(please see http://wwwasd.web.cern.ch/wwwasd/geant4/ G4UsersDocuments/UsersGuides/PhysicsReferenceManual/ html71/node60.html#SECTION04771000000000000000)
You can however try to play with the trade off between the CPU and accuracy.
