Mining balance literally dropped before my eyes!

@1841 (6:41 pm)!!! WE HAVE A PROBLEM!!!  I LITERALLY WATCHED BALANCE DROP IN A SPLIT SECOND!!  SAME ON THE WALLET! It was NOT the $ amount, it was the mining balance!!  Now mining has stopped, ‘restarting’ on its own. 

@1848 it restarted, Active, got HR of 21.  Waiting for updates….@1900, still mining but ZERO increase!

It’s now in dead mining time (mining with NO increase in balance)!!!

See attached from my basic log I keep. 

At 4:38 pm PST, I was at 0.003260.  Literally 2 hrs later I WATCHED it DROP to .003258 and then balance increase just stopped!  I really had hopes for this app, it was gong pretty good and looking like I was finally going to hit my 1st .004 after almost a month, BUT we seem to be being cheated.  We have had many hours of dead mining time, and now I have seen a drop in balance!  What is going on? 

@1848 it restarted, Active, got HR of 21.  Waiting for updates….@1900, still mining but ZERO increase!

It’s now in dead mining time (mining with NO increase in balance)!!!  Between this and a drop in balance, we seem to be being cheated! Shutting this thing down. I will do a total uninstall and reinstall of Norton sometime this weekend and maybe try mining again but I lost trust in it!  Would be nice to get my balance back but, we never did get any 'jump' from the dead mining like one of the Admins told us we would.

Same here from 0.001600ish to 0.000700ish  :(
