The problem is getting worse. Lots of troubleshooting to rule out any other possibility. Same problem with wired and USB keyboards (which work great when connected to other KVMs and directly to laptops). Seems to be on the input side as the problem occurs on both outputs. The problem is also intermittent: it can function normally for several days and then skip three out of four keystrokes for several days.
