Anyone else having issues with right-click copy paste dropping first character highlighted in view log files

In virtualmin under logs and reports / Apache Access Log if i see something I don't like i usually right mouse copy and past the ip into google or tcpiputils.com to find out where the bad action is coming from. I noticed starting a couple of weeks ago that the text you left mouse hold and highlight then right-mouse copy/right mouse-paste is missing the first character in highlighted string.

Not a huge deal, but odd since worked wonderfully previous to this .

using ctl-c / ctl-v does not seem to do this. multiple computers, both firefox and IE (i dont do chrome) do the same.

Using authentic theme btw.
