If you set get_config().Global.exec_lines and/or get_config().Global.exec_file in your config file, it upsets the line numbering. When you start up, it looks something like this:
IPython 0.11.alpha1.git running Python 2.6.5
Notice that the first line is numbered 10 - that's confusing, and seems to me should not be happening. It didn't in Python 0.9, did it?
It is, however, consistent - input lines appear in the In list, and there is no output, so nothing appears in the Out dict.
Note that this will be taken care of by #363 when merged; thanks for the report!
run_cell(exec_lines) now called with 'store_history=False'
This prevents config file defined exec_lines from showing up
in the history, and results in input counter always starting at 1
fix changing volume not showing up on other computers. closes #125
