Bug Description

Mint 13, Maya
Cinnamon 1.4

Workstation CPU:
Dual hex-core AMD Opteron 2427, 2.2 GHz
Supermicro H8DA3-2 MBd

Dual monitors
Nvidia GeForce 8400 GS/PCIe/SSE2
3.3.0 NVIDIA 295.40 (installed using Additional Drivers app)
1 DVI output, 1 VGA output
Primary monitor is set for VGA

Hot corners do not work properly with dual monitors. Regardless of the hot corner setting, the top left corner of the secondary monitor is always a hot corner. The left corners of the primary monitor will respond when a left hot corner is set, but not the bottom left of the secondary monitor. The right corners of the secondary monitor will respond when setting a right hot corner, but never on the primary monitor. The icon and "wave" notifications do not appear consistently in the expeected places.

I really like Cinnamon, BTW -- you all have done a great job. Just want to report the problems.

I have the same problem on a new mint box pro, with dual monitors.

I want to turn off the hotspot in the top left hand corner that switches desktops. Several times a day I move the mouse there when going to the file menu in Firefox for example, and if I overshoot the mouse pointer FF minimises and I have to re-open the desktop.

If I go to Menu >Preferences >Cinnamon Settings > Hot Corner, i saw that 'Hot corner enabled' is ticked, and Hot corner position is Top Left.

I uncheck the Hot corner enabled box and close the dialogue, but the hot corner is still active in the top left corner of my screen.

If I go to Menu >Preferences >Cinnamon Settings > Hot Corner again I see that 'Hot corner enabled' is now not ticked which shows that the change was saved, but nothing has actually changed as far as the 'Hot corner' being dissabled.

Still an issue ..

System: Kernel: 4.10.0-27-generic x86_64 (64 bit) Desktop: Cinnamon 3.4.4
           Distro: Linux Mint 18.2 Sonya

Display covers both monitors; 2nd screen has no hot corners, only the primary screen has. (I.e. in my case "top left" and "bottom left" are in the middle of the display, instead of on the left.)
