Quotebut I'm afraid that the keyboard issue still persists, as the information given in the keyboard creator isn't focusing when in list controlsYou are right, but upon closer inspection, list views behave the same way no matter where they are used in OpenMPT. This appears to be a quirk of the list view control. Since OpenMPT is built entirely on top of standard GUI controls provided by Windows, there isn't much we can do there, and you will probably find the same issue in any other software using the same list component.
QuoteIt looks as if even though the install update keyboard command *Alt+I* is given to install the update, nothing actually happeneds when pushing the command.Alt+I is the default keyboard shortcut for switching to the instrument library. User shortcuts take precedence over accelerator keys. If you want to be sure that custom keyboard shortcuts are never in conflict with accelerator keys, you would have to find all shortcuts assigned to any of Alt+A...Alt+Z and unassign them or assign them to a different key combination.
