camera help??????

I need to stop my fps camera from moving when i hold H key.. i really don't have an idea why how to do it...

anyway the purpose of holding H key is to get a hint, when i click a guiTexture it will pop out some particles to give the player a hint of what he's looking for.. the problem is when the cursor is not hidden and if i move the cursor to press the guiTexture the camera moves. I don't want that..

so guys i need some help :D

and thanks in advance :D

object.scriptname.enabled comes to mind - use true and false to turn it off and on as required.

Also note : there are/were multiple scripts controlling the FPS character.
