The PgUp and PgDn keys do not work correctly per Windows UI specifications when browsing through the presets. Very annoying. This is a bug in your UI as both keys need to work per the Widows UI specification.
Actually … the keys do not work at all.
This needs to be fixed ASAP - browsing presets is a PITA.
I have changed this to a Product Feature Request … because remember that an app doesn’t have to use all the navigation keys such as directional arrows, plus Home, End, Page Up, and Page Down.
I don’t think either Impression or Glow will be updated as they are incorporated into Studio now.
