May 11, 2017. In late April, the Hitachi engineer replaced a key computer board in the FESEM and rebuilt the hard drive from scratch. As a result, the computer should nmo longer lock up and we can close the software without fear of a problem.
In the last 2 days we have seen a parallel white lines rapidly crossing the screen. Yesterday, I had to shut the PC down to get it to stop, today I only had to restart the software to correct the problem. I have contacted Hitachi for more information
