I recently bought this keyboard and picked it up from the seller's distribution center (there's a thread in Great Deals about this particular model). I'm having some really odd rollover issues that are confined to very specific keypress patterns in particular. When A and W are pressed at the same time, for example, the entire rest of the row from those characters on does not register keypresses. Only Q will register as the third rollover key with that combination. Worse, holding down O and K at the same time will render the entire two rows dead to a third key rollover; this includes literally every two-key hold that progresses in a diagonal down-left pattern from the top-mid right of the keyboard to E+S. Keys pressed top to mid in a diagonal down-right pattern disable 2 keys around the keypress, with the rest being recognized (i.e. E+D disables the S and R keys, but no others on either row).
When AS is held down, Q, W, Z and X will not register as a third rollover key. J+N disables only H and M, which seems to go against the hypothesis of the whole diagonal down-left top to mid pattern being applicable to the bottom row as well.
Pressing any two keys in a diagonal down-left pattern from mid to bottom disables every key in either row for a third rollover also.
Does anybody who knows anything about electrical engineering, circuitry, etc have any idea why these particular patterns are cropping up?
I don't particularly mind using this keyboard as a typing model for work or writing exclusively, but it's disappointing that its uses in gaming have to be limited with a standard WASD configuration.
