Hi Hugo,

My question would probably be surprising for you! Do your LegendPanel use  
a "border" layout shared with an other panel (a MapPanel precisely? I got  
a similar bug: this one appeared when I collapsed/expanded the LegendPanel  
after removing a layer.

I'm not sure your problem is related to this one, but perhaps?

Geoffrey
