In Windows 7 the 'busy' cursor is a spinning circle, so if your mouse cursor is flashing there may be something else going on.
But if the mouse is showing busy constantly then something is doing that and it is a process of elimination to find the cause.
First thing, check what Processes are doing in the Task Manager. Right click the Taskbar and select Task Manager. In the new window select the Processes tab, then click the option at the bottom to "Show processes from all users". Now, click the CPU column to list processes in CPU Usage order and see what process is continuously using cpu time.
System is Windows 7 home 64 bit with amd athlon II 255 Processor 3.10 GHz and 4gb of ram. Avast anti-virus. I have windows firewall on, but haven't really made any other changes.
My cursor flashes the busy symbol about once every 4-5 seconds, and it does so whenever the mouse is on the desktop or anywhere it shows the regular icon. When inside this text window it changes to the text cursor and ceases to flash, however. I changed the icon only to have the new one act the same.
I ran a full scan and boot scan, and found nothing of any concern. Any ideas on why this is happening? I have seen lots of posts but most issues seem to be related to programs like word or files.
Thanks for any help
