In the process of getting my computer all virused up then getting it UN-virused, some keyboard setting(s) must have been radically changed. There's is no immediate response to my hitting (pressing, actually, but HITTING is TEMPTING. When I press the spacebar, it inserts the space between the first and second letters of the subsequent word. Additionally, the first lettero of the following word is crowded against the last letter of the preceeding word, like so:
Thequickb rownf oxjumpedo vert helazyb rowndog.
Further, I can insert spaces between words by putting the cursor between them, pressing backspace then spacebar, then the first letter ofthefollowing word.
After the space is inserted, there is a pause, followed by the cursor & all keys to the right of it scurrying to the right, as if I'd held down the space bar. This'll continue until I stop it, by pressing either the backspace or delete keY.
The fact I that can reproduce these behaviours with every key I've tried suggests to me that it's something uniformly affecting keyboard operations instead of random glitches.
I've tried clean booting, deleting keyboard operators & re-installing,wiping the drive & reinstalling Windows 7.
Page Up/Down keys work, but arrow keys do not. The "w" key also seems to show up in fainter shade than other letters.
