I got a brand new one this morning. I like it so far but the software is completely confusing. also, small annoyances like that fact that when i even tapp the desk the mouse icon wiggles slowly down the page, even when pressing keys. And also setting up profiles seems to be a bit dodgy as the name of the profile doesnt even appear in the place where it should. If any one has one, help would be greatly appreciated. Also, configuring it so the top side button is foreward and the bottom one is back doesnt seem to wasnt to work, althoguh it did earlier.
