WM_CONTEXTMENU with TrackPopupMenu displays the menu, but when I move my mouse over the popup items (the ones with the little black triangle to the right), their submenus do not auto-display. I have to click the item to get the submenu to display. Funny thing is that it use to work and now it doesn't, so I must have added some code somewhere that has affected things. I'm just not sure what. Any ideas?
