I am using a laptop that is the HP Pavilion dv4 Notebook PC.
The OS being used is the 64-bit Windows 7 Home Premium.
I am using a wired mouse.
Recently, I have cleaned the screen and the keyboard of my laptop.
When restarting the OS, I have found out the problem as follows:
- When opening Google Chrome browser I move the mouse pointer over the taskbar, it stops functioning even I cannot click the Start button
- The same problem has occurred to IE browser
- But when using Firefox, the mouse works properly as usual
Please help me fix this problem!
