I have notice that 1970 and earlier version doesn't have this problem... BUt once i switch to 3186/3188 its getting annoying... When i swtich from my mac osX to Windows XP with virtue desktop.. I use the key "windows+shift+up".. so when i swtich to windows... it rmbs my last key i push for my mac osx.. so the windows start up and it just right clicks on windows xp... How i do make it not rmb the last key i push for macosx... like in 1970?
