Rated 3 out of 5 stars
Needs work, but promising.
Dust-me worked for a few sites after first installation, but now clicking on the duster icon results in a split second or a few minutes of icon animation (depending upon size of site) and no apparent popup window.
I am running W/7 with aero desktop. If I mouse over the Firefox Icon in the task bar, I can see a transparent window was created -- clicking on the transparent window yields a transparent window!
If I right-click the duster icon, choose Preferences, Data tab, and direct the output data to a folder that I can find later (not sure where the default folder is) I can verify that data was created and it appears correct.
I have no clue as to what I did to make Dust-me stop working. After the initial test that worked, I did other things for several hours, put the PC to sleep overnight, and when I tried again I got the transparent window effect. Restarting Firefox, rebooting, uninstalling and reinstalling Dust-me has no effect.
