I have problems in using solpartmenu.

1. I was trying to create horizontal menu with round cornered menu tab,  the menu should react to "mouse over". I tried to use LeftSeparatorActive and RightSeparatorActive for menu tab side images to get "onmouseover" effect, but what I got is images set in LeftSeparatorActive and RightSeparatorActive only react to "onmouseclick".  How do I make the menu tab separator images to change on mouse over?

2. My submenu tabs don't use background image set in submenucssclass but inheritly use background image in MenuItemCssClass. That makes my submenu background the same as main menu background, how do I config if I want to make them different?

3. My first level submenu has about 7px indent to the main menu, is there anyway to remove the indent,  make submenu vertically in line with main menu?

4. How do I add arrow to the right side of submenu tab text?

Thanks in advance for your help
