Windows 7 forum: New Laptop Windows 7 Bluetooth Mouse Jerky after boot/reboot

New Inspiron 5720 laptop. i7 quad, 8g ram, Home Premium. Delivered Thursday this week. Updated all the way, AVG antivirus, Comodo Firewall (FW only!). every startup, every reboot, the blue tooth (Targus and MS) mouse is incredibly NOT smooth. 20% more and it would be unuseable. If i go to the View Bluetooth devices and remove the mouse then fresh search for it-find it-install it, now the Bluetooth mouse is as sweet and pleasant as can be. If I remove it before shutdown the find and add after boot, same thing. But just reboot and it's back to horrible. A wireless mouse (with dongle thingie) works fine, anytime. Phone and online chats with Dell have led to them pointing me to the Intel site for the driver package
BT_2.2_s64.exe. Downloaded, installed, exact same behavior. Reboot and the mouse needs a kick- remove and rediscover and it's fine. Uninstall the Intel package, base MS/Win7 bluetooth enum, same thing.
Found similar but more comprehensive driver and installer package for the Intel 2200 half card wireless on Lenovo website. (300+MB!) Installed it, at least it does Install the Intel ProSet package into running/starting services.. Same mouse behavior. Tried setting some things to 'Auto-Delayed start'... no help.. For right now Dell is sending a new wireless card but I suspicion it will be zero help. Search the internet and I see a lot of people have the similar problem, some even when the close the laptop lid and reopen- or half a dozen variations on this.
Even more frustrating is I have a slightly aged Inspiron N5010 Laptop with W7 home prem that these same mice work flawlessly with it;s Dell 365 bluetooth module. I'll Try just about anything- I don't see how a full reload will help because it was this way from the first hours. Some trick in the registry-I'm game for it- whatever! If I knew what to put in it I'd try a Bat file in the startup folder to remove and search during the last moments of boot. TIA
