I'm running 2.1-update1 on milestone but still have this issue. it
appears intermittent, however. generally the app tray loading appears
to be lazy, even when lazy load is disabled. if turning turning lazy
load on, then off again does not help you, I've found that doing a :
settings-applications-manage applications-home++-force stop can help.
after restarting home++, app tray was still slow the first few times,
but then after a few minutes it seems to stay cached and become fast
