Newbie has wonky mouse performance in Sonar Professional (SOLVED!)

Hi... I'm having a problem on a Dell XPS 8500/Windows 7 Home Premium/64-bit. Using a fairly new Logitech wireless mouse/keyboard combo, and the ability to engage the Control Bar buttons by clicking them is hit and miss. For example, sometimes I can click the "play" button in the transport and it will work, sometimes not. Using the space bar on the keyboard to play/stop works consistently. 
 
Sometimes, if the mouse is working with the transport buttons, it won't click the "Smart" - "Select" - "Move" - "Edit" etc. buttons on the top left of the Control Bar. Everything else below the Control Bar seems to work fine... except my mouse pointer disappears when I "grab/drag" anything.
 
Anyone having an issue like this? Any known bugs with Logitech wireless mice? Tried looking for latest drivers on Logitech site, but no luck finding any.
 
Thanks. Driving me crazy!

The mouse will consume battery power quicker than the keyboard. Battery level and distance from the USB receiver are important. My receiver is on an extension cable and only about 8" from the mouse. Interference is another possibility, but less likely.

FWIW, you do not need SetPoint installed as Windows supports up to 5-button mice natively, but will not get a low battery warning. Some have mentioned issues with SetPoint, but I have not experienced them.

Another side point is to clean the optics cavity regularly (gently with a q-tip), since the mouse can continuously respond to "motion" which both drains the batteries and may also interrupt the signals from it.

Hey everyone... thank you for the replies. Yes, Bud, seems the way to go is to try a different mouse. Would like to stay wireless, but I have an old wired mouse I can try for troubleshooting, just to eliminate variables. Weird that the mouse works fine in some areas of the Sonar interface, but not others...

 I know this isn't exactly Sonar related, but it may help. I ran into an issue last night after windows 7 installed some updates. My wireless mouse would work, but then pause for a few milliseconds and then continue working. This happened about every 5 seconds or so and was quite irritating. On the bottom of my wireless mouse there is a little red "connect" button. I pressed it and my issue went away. You may want to give it a try.

In addition to the above, try different USB ports if you can.

 Also, a very good idea.  I'd start with the one you are currently using for your wireless, and if you still have the problem try another USB port.  Key to good troubleshooting: one variable at a time.

The reason is screen settings. Sonar doesn't support windows 125% and 150% settings.

Mystery solved! Not sure if Adq (above) is the tech that replied to an email I sent in, but yes, 
 
FROM TECH SUPPORT:
<<It sounds like your screen resolution or dpi may need to be increased on the problematic monitor. 
Please take a look at  and follow the instructions contained within and let me know if this makes any difference for you. Also be sure your screen resolution on both screens is at least 1280x800, the minimum resolution supported by SONAR.>>
 
My monitor resolutions are both 1920x1080 and I had increased the screen setting to 150% a long time ago -- okay, my eyes aren't the best, and that HD resolution can make things really tiny. So I set it to 100%, as the KB article suggests and the problem was solved. I bumped the screen up to 125% and it also seemed to work -- so a happy median for my eyes. 
 
Thanks to everyone who replied. 

 
Glad to hear you got it figured out Billy.  The moderators appreciate you editing the title of your post to add:[Solved]
That way people who might be looking for the same thing will know they can find an answer here.
 
Cheers!
