It might be a mouse issue -- the touchpad works normally. With the mouse though if I start Fluff from wbar, a left or right click-and-hold anywhere on the screen (besides on Fluff) pops up the Fluff File Manager menu. If I l click and hold on the Fluff panel itself I get the Fluff Directory Menu, then it goes to the Fluff File Manager when I release the button. Other windows seem OK, but I'm running a very minimal setup (basic TCL/wireless installed from CorePlus, Namorka, and Fluff).
Since Fluff works fine on my desktop box I'm hesitant to call it a Fluff issue. I haven't really looked into whether I might need a different driver or something for this mouse.
