Cursor does not change and dock is not responding

Question

mac mini mid 2011, 10.9.5 logitech wireless keyboard and mouse (wave). Dell 20 something inch monitor with lighting to mini display to hdmi.
My cursor will get stuck on the arrow and not change on text input fields or the index finger to select links. If it does change at some random point, it will stay to whatever it changes, until it decides to change again. This will change every 10 to 15 minutes depending on how heavy I'm using it. The dock is also not responsive. If it is hidden, it will not pop up, if it is up on magnify, it will not magnify. Once in a great while it will magnify, but only to one spot and will not change.
In addition, when I hover the mouse, things will not appear or recognize the mouse, like a print or zoom on the bottom of a pdf, or even a field on some web pages. It will not allow me to select some fields. www.jobs.ca.gov is the best example, I can not type a search or select a position. One time I even had the system settings icon stuck to my mouse and could not put it back on the dock. It followed the mouse, when I would single click, it would stay where it was, unless it was at the dock. If I double clicked it would open.
I've only had this mini for about 4 months, this problem has only been going on for the past couple weeks. There have not been any changes in those past few weeks that I'm aware of. I did upgrade to 2 4gb ram 6 weeks ago and did a software update to 10.9.5 about 2 weeks ago, but I was hoping that would fix this problem. It did not.
I was also having tons of problems with safari about a week ago, but a reboot into a certain mode, then back to normal reboot solved that.
Thanks everyone in advance for you time and help.

Answer 1

I had this same problem and was searching for answers. I also prefer using a circle instead of crosshairs. I hope you've figured it out by now, but, if you haven't, here is the answer (I am using Elements 9, but, it should work for other versions I think):
1. Open up Elements Editor, Click on Edit, Click on Preferences, Click on Display & Cursors.
2. Under Painting Cursors, select Full Size Brush Tip
3. (optional) - if you want crosshairs within your circle, then also select Show Crosshair in Brush Tip.
4. Click ok.
Now use the brush, and it should have a circle to use.
P.S. Sometimes if you have your Caps Lock key on, that removes the circle as well.
