Getting "Not Responding" after every keystroke when using TaxAct. I see the message and then after about 10-15 seconds if will tabulate. It is literally happening after every key stroke. I have never had this happen before. My laptop has Windows 8.

I would like to know some information about the issue so that we could help you better.

1. Did you make any hardware or software changes to your computer prior to the issue? 2. Is the issue specific to one program?
I appreciate you for providing details about the issue.

If a program is not responding, it means the program is interacting more slowly than usual with Windows, typically because an issue has occurred in the program. If the issue is temporary, and if you choose to wait, some programs will start responding again. Depending on the options available, you can also choose to close or restart the program.

This issue may occur due to software conflicts or due to slow Windows performance.

I would suggest you to try following methods and check if it helps.

Method 1:
Perform clean boot and check the issue.
Refer this article:

Clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program.

If it does not help, use method 2.

Important Notes:
While running disk clean up on the hard drive, if any bad files are found on the hard drive and when disk clean up tries to clean those files, any available data might get lost.

After you have finished troubleshooting, follow these steps from section “How to reset the computer to start as usual after clean boot troubleshooting” to reset the computer to start as usual.

When you close a program that has stopped responding, all files or documents that you've opened using the program are closed, not just the one that you're viewing when the problem occurs. Some programs might try to save your information, but it depends on the program that you're using. To help prevent information loss, save your work frequently.
