Volume Slider Moves without Mouse Movement and Effects Knobs Values Jump

Hi all. Sorry to add more to what appears to be a busy forum! Here's my issues:
 
When I adjust volumes in the track view left side panel (Volume, pan, gain, Mute-Solo-Records etc) I click the Volume slider and drag it to the left or right to change the track volume. But I do this while the song is playing so I can listen to the level. What I do is drag the slider to one side a bit to change the volume and hold the left mouse button down and listen for a few seconds to see if I like that level. I've been doing this for many years and it's always worked fine.  
 
But now when I stop moving the slider and keep holding the mouse button down, the slider will keep moving in the same direction even though I'm not moving the mouse. So, if I'm raising the volume and stop moving the mouse at -9, the volume will keep getting louder - -8, -7, -5 etc. This is a new feature that just appeared a few weeks (or couple of months) ago although it doesn't seem to happen every time. Sometimes I can make it happen by clicking the control twice fairly quickly, or after double clicking.
 
The question is: Is there some way to turn that off?
 
And second, in some of the effects, specifically the Cakewalk Tempo Delay right now, when I try to adjust the values by turning the knobs, the values jump around a lot. I've been using that Delay for many years and never had a problem but suddenly today if I start to adjust a delay time down a bit it instantly jumps to 0.00. Then when I start to go back up it will often jump to the maximum time. If you click in the dead center of the control it works a bit better but will still jump if you change direction.
 
Same thing seems to be happening in the other Cakewalk effects.
 
Same question: Is there some way to change it back to the way it worked before? 
 
Just for comparison: The knobs in the Nomad Factory Echos still work fine..
 
That is all! Overall, I'm pretty happy right now. A few nights ago it crashed twice.  The second time was a full computer lock-up but it's been fine since and crashing is fairly rare. I think it might be mostly due to my old emu 1212m card. I just did the new update today (a few minutes ago to see if it changed the 2 behaviors mentioned above.. and no, it didn't).
 
The only other comment I'll make is this: When Sonar crashes I usually cannot end the process (SonarPLT.exe). I have to reboot to get it working again. I have never had that happen with any other program! Rebooting is pretty fast with an SSD but still, it's a little inconvenient.
 
EDIT: I take that back... it just crashed again. All I did was copy an audio clip (CTRL-CLICK and drag). The screens went black and the computer started booting up again. 
 
EDIT 2: Wow, it just crashed again. All I did was hit CTRL-S (which I try to do after VERY little thing I do now) and my 2nd monitor suddenly turned pink... no keyboard, no mouse. Nothing. Had to hit the reset button. It's become VERY difficult to accomplish anything with sonar lately...  It may be Windows 10, or it may be my sound card but this sure costs me a lot of time.
 
On another note: Every time this happens many of my clips wont display a waveform any more and I have to go to the Picture Cache and delete all those files. It would be nice if there was a way to rebuild those inside the program.
 
 This is Sonar Platinum, V: 22.6.0 Build 26 [2016.6] - x64 running on Windows 10 with all updates installed.
Computer: CPU -Intel i7-3770  3.4ghz, 16GB RAM
C: is a 250GB SSD
D: is a 3TB hard drive (WD Red)
G: is a 250GB SSD - all cakewalk projects and data on this drive
 
Thanks guys!

Also if you have another mouse, try that. Mice don't last forever and I once had one that did intermittent "cursor creep." If it's a wireless mouse, check the batteries.
