Nautilus: Different response when clicking minimized Nautilus with Mouse vs Touchpad.

[Idad]

I want to ask something,

I have already observed this strange behaviour since Ubuntu 13.04.

I know I can Maximize Apps in Unity Launcher (which is opened and minimized) with Mouse Scroll Up and Also Clicking it (if it was not multiple instance, as multiple instance will evoke select windows behavior).

This problem was limited to Nautilus only.

When trying to maximized a Single Nautilus in minimized size, there are different response when clicking the Icon in launcher between Mouse Click and Tapping Touchpad.

- With touchpad, the Nautilus is Maximized,
- With Mouse Click the nautilus is not consistent between Maximizing the MInimized Nautilus and sometimes Creating a new Nautilus window (the minimized one still minimized).

As Example:
A one single Nautilus Apps is opened and minimized in Launcher:
- Touchpad Left Click --> Maximize the Nautilus
- Mouse Left Click --> Open another Nautilus , now I get 2 Nautilus

I have posted this similar question in AskUbuntu (http://askubuntu.com/questions/720342/clicking-minimize-apps-to-maximize-it-in-unity-launcher-with-mouse-and-touchpad) but i got no answer, so I confuse is this a really bug or not. What makes me consider this is a bug, I never experienced this case in older version of Ubuntu (< 13.04). This problem occurs since ubuntu 13.04 and newer.

This is my first time reporting a bug. If I am in worng place to report this, or perhaps I should report this to Nautilus developer, please guide me to do it.

Many thanks in Adnvance :D

PS: This problem was limited to Nautilus since 15.10. When using Ubuntu 13.04-15.04 this kind of behaviour (i.e. maximizing Applications by clicking it with mouse vs touchpad, which the Apps are minimized in launcher, will evoke different result) is observed in all apps which are minimized. I regret not to report this earlier.
