Need handholding, I recon

I am proving myself completely inept. I paid retail for the MX900 yesterday, all started fine & am now having troubles. Perhaps someone who has the TM300 working well with the mouse, preferably that MX900 will want to PM me and we can talk this through on the phone.
I had it working ok without the setpoint software - since I didn't use the USB bluetooth hub the SW didn't install, so I skipped it. When I used the bluetooth icon to search for the mouse, it found it & then XP went thru a embedded driver install for the MX900 & all was fine. Mouse worked, and when the mouse went to sleep, all I needed to do was jiggle it, and it started working again (unlike my experience with the EPox mouse). The only button that didn't work was the appication quick-switch; which was similar to other's experiences.
Then I left the laptop idle long enough for it to go into sleep mode. Upon waking up the machine I couldn't get the mouse to respond. I tried the "Search for Bluetooth Devices", and no combination of prodding has seemed to work.
I plugged in the external USB hub, installed the intellipoint software, grasping at straws. Upon power-down, removing the hub, and power-up, I cannot get the mouse detected.
That aside, I'm not sure I like the shape of the MX900. The pointing sensitivity was defaulted to slower than what I needed to cross the entire screen without picking up the mouse, and when I went into windows mouse settings, it of course changed the touchpad sensitivity right along with the mouse. Not too bad, but the windows setting wouldn't stick upon reboot. So that's when I started picking up the mouse, and the MX900 shape is poor for that.
Is this why some folks rave about Macs?
