Thanks for the help c-attack. I switched to 2.4 ghz and successfully used iCue's Instant Lighting to force the logo off. After reading the mouse specs it looks like the 2.4 ghz is where the mouse uses Slipstream and a little experimentation shows that Slipstream also depends on the dongle.
One problem still exists though... when I switch the mouse from 2.4 to BT it looses the setting that was successful with the mouse in 2.4 slipstream mode. Any idea on how to get the setting in BT mode too?
NVM: I redid the pairing of my Harpoon to both the 2.4 Slipstream and BT. And while it was connected through 2.4 I also enabled power saving mode. That appears to also turn off the logo, which makes sense. Then I re-paired the Harpoon through BT and all is well. The Logo indicator is not flashing at me and the I'm in BT mode.
