When I totally clear the Picture Cache scrolling and dragging is pretty smooth and flows okay....as soon as I start to work on the project in hand, the scrolling and dragging soon starts to become a problem again. There are not that many Picture Cache files built up but it's causing a problem until I totally clear all Picture Cache again.

Are there any adjustments anywhere I can make ?

Sonar X1 ...Windows 7

Exclude your antivirus realtime scanner from the picturecache folder.
Update your display drivers.
Make sure you are on Sonar X1D.
Run windows update.
Defragment your hard drive.

Hi. You do not by any chance have scroll lock enabled on your keyboard?
All the best.

Thanx ..I gleaned some info from the forum and enlarged my cache from 500 to 1000 which seems excessive but it seems,so far, to have worked ...I don't know how ...maybe it's just zapped a gremlin ...

If the problem returns I'll try the suggestions above...

Problem is back.. This is quite bad at times . I have to stop working, close the project, open Cache and clear all files then resume. After that the problem is gone but gradually it returns. It only needs a hundred or so files in Cache to start all the stuttering and jerking ...also the now line doesn't flow it hops along.
I've tried all the suggestions above but it hasn't made any difference at all.
Apart from Picture Cache I haven't a clue what to try .

The PC is for dedicated music only ..not connected to the web. No anti virus or anything, there's no other problems on anything, all graphics and display are set to optimum.

I had a somewhat similar issue previously. I updated my graphics driver and the issue went away.

Thanks...I updated the graphics a couple of months ago...I 'll try another upgrade as there's nothing else I can try at the moment.

Windows 7 graphic driver is up to date and so is the motherboards....still the same problem, is my only option now a graphic accelerator card ? If so any recommendations ?

You shouldn't need a dedicated graphics card just to run Sonar - it's not a graphic heavy program like many games are, but if you do need one, make sure it's cheap & fanless! No point in spending mega bucks on what would be overkill.
 
What is the location of your picture cache? In fact, describe your entire drive structure, let us know what is being stored/written onto each drive.

You shouldn't need an additional display adapter, but display drivers or the firmware can be cause of latency/jerkiness. See if you can borrow a graphics card perhaps to see if it makes a difference.

I would update the motherboard BIOS first to see if it makes a difference and also post check #2 again.
 
Also download a copy of latencymon out to see if anything is getting in the way. Process monitor and process explorer could also help you here from sysinternals/Microsoft.
 
You write "The PC is for dedicated music only ..not connected to the web. No anti virus or anything, there's no other problems on anything, all graphics and display are set to optimum."... and then you wrote "I've tried all the suggestions above but it hasn't made any difference at all. " - So how did you run windows update (as I suggested) when you are off the internet?
 
We tend to get a lot of issues with offline machines in these forums mainly because software dependencies are not up to date.
 
If you have no antivirus first thing I would do is do a scan with something like AVG AND malwarebytes. Never assume that you don't have a virus or malware just because you are off the internet. You have to get your software and data from somewhere, whilst you may have reduced your chances of getting a virus that does not mean it won't happen...
 
Don't forget to back up...

Cheers...
