I have Vertical Solpart menu , everything works great except when I try to turn usearrows="true". There is a background image that displays a small arrow on the ft of each Menu item.On turning UseArro- "true" the small arrow to show child pages exists occurs but along with it the background image occors too on the rt of each menu item.( same place as the use arrow arrows appear) any suggestions?

The short and simple answer is, this is all in the styling of the menu. You can remove or replace the background images in the skin.css file.
