I have an HP Probook 4540S operating on Windows 7. Every so often I will be typing a document or working with the keyboard and it 'freezes'. For example, I will be drafting an email and all of a sudden I cannot type numbers (it enters the symbol above the number) and when I try to click into the body of the text, it selects everything below the spot that I click. Is there a button/tool for this? Am I accidently pressing something that i don't know about?
