Mine is also 2.6.0, I have what I think are default settings--I have scroll speed in the middle and I have acceleration turned off (b/c I hate that feature). Are you having the same issue with loss of focus described where as soon as you scroll the cursor goes from the white windows one to the black mac one? I also haven't tried a full uninstall then re-install. I used the in-software update feature to get the latest LCC.
UPDATE: OK, I was TOTALLY WRONG. It wasn't the drivers that fixed my issue--it is still broken. It was the process of updating them that caused my mac to unload the Logitech drivers and use the default mac drivers. The default drivers, as are mentioned in the archived thread work fine. After rebooting to verify that the Logitech drivers were active, the problem returned. At this point, I'm not sure where to lay the blame, is this Parallels or Logitech? All I know is that it worked in PD3 and now it doesn't so they both probably share the blame. Parallels for changing how they handle the "window" mode and Logitech for not honoring the active window property. sorry for all the confusion I've caused. It is in fact still broken.
UPDATE 2: I've submitted a bug to Logitech, let's see what their customer support says. Maybe someone in one of theses companies will care enough to fix the issue.
