In KDE 4.1, Click the KMenu, then Click Applications, then click any folder, we will see a left arrow at the left side of screen and we click at the left side of screen we can back to the folder.

This is easy to use in KDE 4.1, since we uses the "sweet point" concept, put the mouse pointer at the left side of screen and click.

However in the newest KDE 4.2, I can no longer click at the left side of screen:



I know there is a window decoration border now, but it is important to be able to click at the left side since it is easier and the use of "sweet point" (i.e. mouse click at the 4 screen corners and 4 screen sides) is one of the basic philosophy of KDE4.

PS: I'm using kde-nightly from project-neon.

For verification purposes, I'm unable to click it at the left side of the screen as well, but clicking on the blue bar works. It appears that the small bit of space between the blue bar and the left side of the screen is killing the edge of screen clicks.

This is primarily because many bugs were fixed in Plasma for KDE 4.2, and fixing the drawing of borders and making them present was likely among them. Therefore breaking this was probably not deliberate. You should feel free to report this as a bug.

I'm found a bug report here

Please help confirm it if you feel necessary.

Thank you all.
