When i click left on the touch pad menu appears

Check the touchpad software to see if there an option to switch the buttons; Usually there is aplet that runs and show in the taskbar.

Also in Control panel, in mouse options.

checked that..still the same..

Check to see if the CTRL key is not jammed down or the Properties key is not stuck.
Just tap the keys lightly to see that they are free and then give it a try.
Go into the control panel and check mouse options:
First panel itself has an option which says "Switch primary and secondary buttons" makes sure the box there is unchecked.

its unchecked.. problem persists

then put a check in the box and try it.

hmmm

isn't that a logical answer?
Somehow your touchpad has ended up confusing the primary and secondary button.
So to unconfuse it you need to reverse the senses of the touchpad.

touch pad has gt a sense too? k..if u cant help me...jus sssshhhhhhh

That attitude ain't gonna get you too far...
Solve it yourself in that case.

attitude?

well...thx fr ur tym..

Sometimes, setting it, and resetting it, rewrites the setting to the file in Windows, because the file may have gotten replaced...so ticking and unticking and reticking will sometimes fix it....hitting "apply" or "okay" each time.

Tried all the possible ways..donno wats wrong with it..menu appears with both left and right button..

Do you remember when it started? If so, you can use Windows System Restore to go back to a date before that time.

You could also reinstall the drivers for the touchpad if you can't fix it.
