I been having the following problem for a long time in Ubuntu 10.10.
What happens: When I right click I see the contextual but when I release this button it automatically clicks on the first option on this menu.
What Should happen: Normal behavior. Show the menu and then with left click (or right again) operate on said menu.
This is a USB mouse, is not a hardware error, it works in other computers, and in this same one perfectly when in Windows.
This machine have a nvidia card. Using nvidia-current package.
This problem is more prominent in Chromium and Java applications, also in "gnome-terminal".
UPDATE: in Firefox I get the expected behavior.
I tried already
*changing the InputDevice section of my xorg,
*changing setting in the BIOS (Asus motherboard) legacy USB support on and off.
*creating another user (clean .profile ,etc)
*log Gnome as "safe-mode" this means that compiz, and all other software isn't running
known workaround : click and hold the right button and then release on the chosen menu option.
link with people with the same problem:
Thanks so much in advance.
