retester does not pause after pause button pushed

Condition is reproducible.  In Retester once strategies have begun testing if the Pause button is pressed the program continues to process the strategies.  Example: I loaded 500 strategies into Retester and started the testing.  When the progress bar showed 1% I pressed the Pause button.  The program continued to 100%.  While it is "paused" but still running I'm able to select failed strategies and delete them, something I can't do when the program is running normally.  The log panel displays the pause and resume project messages as expected.  It doesn't appear to matter what currency pair or what strategies are loaded.
