Bluetooth mouse not acting correctly

Question

Hi, Received my brand new XPS 420 yesterday, with bluetooth mouse and keyboard. Everything was included, other than the LCD monitor which I had received as a present previously (Samsung). Everything went in fine, Vista set up great, and I could pair the keyboard and mouse fine. The keyboard is flawless but the mouse is behaving strangely when attempting to resize or scroll Windows Vista, er, windows. Moving the pointer to resize the window would put the pointer ten or fifteen pixels too far to the right, making it difficult to determine where to click, and more problematically, when scrolling using the scrollbar, I'd have to click ten or fifteen pixels to the left in order to grab the scrollbar - otherwise, I'd be attempting to select something on the window behind. There was another thread about this fairly recently and the suggestion was to install the latest drivers. After downloading the only drivers I could find (339MB! for keyboard/mouse drivers? Seriously?), uninstalling the existing SetPoint software, rebooting and reinstalling the new drivers, the same problem existed. Now, I'm at work at the moment, so can't try anything else, but I'm new to Bluetooth devices and honestly wouldn't know where to start. I don't think I removed anything from Device Manager last night so if nothing else works, I'll start removing things at random, but I was just hoping someone here would have more info that would help. Many thanks. (Edited for carriage returns) Message Edited by Sidasta on 12-11-2007 11:53 AM

For what it's worth: I've had my new XPS 420 for one week and am having the exact same problems. I hope you get an answer :). The updated ATI drivers also fixed my mouse. Thanks you both for the solution. FYI, I didn't take any chances. I uninstalled the ATI driver, did a reboot, then installed the updated driver from the ATI site. (driver only). We should promote the new driver for factory installs.

All, The fix is to uninstall the video card drivers, restart the PC, reinstall the video card drivers, restart the PC. Or, just disable Aero.

Let me guess, you have an Ati video card?! :smileyvery-happy:    For some very odd reason Dell has junk drivers on the XPS 420 for the Ati Video cards. To be more specific download the drivers from the Ati website, next go into your device manager and uninstall the video card from the list. reboot. Do not let windows install any drivers for the video card. install the drivers that you downloaded from Ati.     Can we make this issue a sticky?!

Hi,

Yep, it was the ATI video card drivers that needed updating, not the Bluetooth/mouse drivers (as I originally thought). Really can't understand the connection between a video card and a mouse pointer but hey, it works now. Just for the record, I got the latest ATI Radeon drivers from www.ati.com and just installed them using the bundled installer (didn't have to uninstall anything first).

Thanks for the responses! And yes, it seems like a widespread problem and should really be stickied for other people.

I am so glad I found your fix for this.  I've had an XPS420 for 3 weeks and the bluetooth mouse was all over the place.  It would move by itself, go in the opposite direction I was moving it and sometimes wouldn't respond to the mouse movement at all.  I had Dell Tech Support on the phone and he logged in to my PC and disabled most of my start-up programs and said it was a conflict.  NOT.  The mouse kept doing it.  I had already installed Dell's latest ATI driver which didn't fix it.  Now, I've installed ATI's new driver directly from their web site and it fixed the issue. And I didn't need to uninstall the previous driver.  The new ATI driver package seemed to do all of it. This is the first time since I got this PC that the mouse is behaving as it should.  Thanks for the info.:smileytongue:
