So I made my own start orb and when I mouse over it, I get a 1 second "dark gray" box around it (ie no transparency) then it fades quickly to transparent and animates to the 'mouseover' orb... its pretty annoying, what did i do wrong to induce this behavior?
FIXED:
In case anyone else has this problem, Apparently i had stray pixels outside of the respective orb areas. I drew a box around the space starting at the bottom pixel of the top orb, and the top pixel of the middle orb and deleted everything in it, then i did the same for the middle->bottom space, and cleaned up above the top one and below the bottom one - this fixed the weird sprite box i was having.
Also, you dont have to worry about cutting off any type of gradient / glow drop offs since the pixes below or above a given orb are clipped by the task bar anyway
