Single click on folder sometimes opens it

[peterzay]

The following new behaviour was detected today in Ubuntu 12.04:

In Nautilus
- single left clicking on folders sometimes opens them instead of highlighting them
- this is reproducible but only randomly

This bug is attributed to Nautilus, but I suspect a deeper problem.

During the main test session, single left clicking on Nautilus in Unity Launcher just below Dash would hide all open windows. A large image of the Workspace Switcher icon would flash up on the desktop on top of the just opened Nautilus window.

A reboot eliminated this Launcher flakiness.

In gmail with chromium browser, I am not getting proper mouse response.

For example, yellow starring an email required several clicks before taking effect. This is reproducible.

Could you please change the importance to sky high. The GUI experience of Ubuntu no longer works.

Single clicking on the upper window border sometimes maximizes the window.

This is reproducible but only randomly.

Exiting an email in gmail using chromium can result in checking all emails in the inbox depending on mouse placement.

This is reproducible and very scary.

An accidental click on delete sends your entire inbox to trash.

Single clicking to make a VISA payment on my bank site actually double clicked and generated a duplicate order.

Fortunately, the system asked me if I really wanted to do that and declined.

This issue needs an URGENT fix.

Ubuntu 13.04 has the same problem.

My machine with Intel onboard graphics does not exhibit this problem.

My machine with nVidia discrete graphics does exhibit the problem.

On the nVidia machine, Ubuntu 13.10 beta 14-may-2013 liveDVD has the same problem.

Excluding physical removal of the nVidia graphics card which would "resolve" the problem, do you have a workaround?

[peterzay (peterzay)]

The nVidia card is GeForce GT620 OEM rev a1.

I have just made an embarrassing discovery.

I replaced the mouse and solved the problem. Sure wish I had thought of that earlier, it would have saved a lot of trouble.

It is very bizarre for a new mouse to intermittently send a double click signal for a physical single click.

Life is full of rude awakenings!
