Mouse Double Clicks when I only Single Click - Problems

I had this issue on my Logitech Laser wireless mouse M505 model and after of tens of trials and searches to forums this solution from bphillips and confirmation by waigy solved my problem. It does not look it will fix it but it did.

- Turn your Performance Mouse MX OFF
- Remove the battery
- Alternate right and left clicking for roughly 30-seconds
- Unplug the USB receiver and plug into a different USB port (not in a USB hub or extension)
- Replace the battery
- Turn your device back ON

If the issue continues, please try using your mouse while in clean boot mode. To test it you can use the double click speed adjustment in control panel/mouse properties. Set the slider to fast and you should be able to constantly click (up to a few times a second) without opening the folder. Before the fix my mouse was regularly opening this folder with a single click.

How to solve, Windows 7: Keyboard keeps changing language

If you are like me that need to change the windows keyboard to input a foreign language like Japanese you may have experienced the situation where windows keep changing the default input language into something you don't want. Windows shouldn't change the keyboard layout automatically, but it remembers the individual language settings to every application as long as the application is running. To reset the input language to default, the application (process) must be ended and relaunched, or the input language manually changed.

I have researched this subject and have solved this problem by doing the following:

1. In "Region and Language" - tab-> Keyboards and languages->change keyboard->Default input language -> choose your language/country

Hope it helps.
