Adds cover part of what I write when I reply to a thread

[DustyDave]

The strip of adds on the right side of the screen cover part of what I write and all the buttons except reply. I run Win 10 and Chrome. Most of the time I can type through the area I can't see, but if anything interrupts I may have to delete and retype a line.
