Floatign Toolba & Lines Flickering

[Itanium]

Hi All!! Well! I am developing a report designer like in Access but facing two problems. 1- I want to make my ToolBar Floating. So that my tools float over my designed area rather than making it fix on form. 2- on same designer I have to draw lines. when panel is repainted then all the lines disappear. SO i added them in an arraylist and repainted them all. But now whenever mouse is hovered over the panel all the lines start flickering. Thanx in advance :) sorry for my bad English.
