I am glad to tell you the problem is cleared.
I don't know if there is a relationship but it started just after I remove the PalettePicker extension.
I cleared all my HD and re-installed all. But at this point I still had the same problem with SearchForBoss.
I Unisntalled Search for Boos and re_installed it. > Now, everything is perfect.
Happy New year to all WebAssist Team & members !
