Occasionally I Am Unable To Scroll My Pages.

[anotheoldgit]

My computer screen keeps freezing from time to time.

The dark blue menu border at the top of the page turns a lighter blue and when I click on it my screen is released from it's frozen state.

Can anyone please supply me with an answer?

I'd say that your browser application is 'losing focus'. Only one application can accept mouse/keyboard input at any time, this is the program that is currently 'in focus', and one way of giving a window focus is by clicking into it but poorly written applications can 'steal' focus. It is common that the 'in focus' window has a different colour title bar - you can test this by having a few applications on the screen (not full screen but a bit smaller) then clicking into them.

So I'd say your problem is that your 'scroll' command is going to another application and when you click back into the browser application you gain control of the browser window.

As for what program it is that's gaining focus and why it's happening, unfortunately this is not trivial to troubleshoot.

Some decent suggestions on the link below if you are confident in applying them - the suggestions will apply to all versions of Windows, not just 7.

Which browser are you using, AOG?

Thank you for your answer

Buenchico: Firefox.
And I have been in my Add-Ons Manager, and found this message:

Firefox synchronisation extension could not be verified for use in Firefox so has been disabled.

A similar message is on other ADD-Ons, which have also been disabled.

Could this be part of my problem?

^^^ I'm not sure, AOG.

Try resetting Firefox to it's default state:
1. Go to your list of Extensions and write down the names of any you wish to keep.
2. Go to Help > Troubleshooting Information and click Refresh Firefox.
3. Return to Extensions and reinstall what you want.
