FckEditor panels hide behind the Model Popup

Using FckEditor with asp.net model popup, there a possibility of Property windows hide behind the model popup panel

change the configuration value to higher value than existing
fckconfig.js and find this line:
FCKConfig.FloatingPanelsZIndex = 100005 ;// 100005 value can be changed according to the browser

: These z-index values can be checked using Element inspection facility of Firebug or IE developer Tool Bar, by applying appropriate values for respective panels (using styles) is another workaround
