When I type text on my laptop, sometimes the cursor jumps backwards. Here's an example of a sentence which I have just typed into the question box:
1We 2hold 3theo 6be 7self-evident, 8that 9all 10men 11are 12created 13equal...se 4truths 5t
After the "t" in "5to", the cursor jumps back to the first "e" in "these". It's not an application-specific problem; the same thing happens when I use Notepad and Notepad++. Curiously, "t" seems to the most error-prone key. Have you ever experienced something similar?
* Lenovo G560 laptop
* Windows 7 Ultimate operating system (64-bit).
Things I have tried which didn't help:
* Re-installing Windows 7
* Running a full virus scan with Microsoft Security Essentials
