When a user has two monitors and the primary monitor is to the right, popups appear on the left monitor (taskbar notifications, etc). This is due to an error in the way the program checks for the number of monitors.
Fix:
Edit Line 2025.
Replace the line:
for my $i (0 .. $monitor) {
With:
for my $i (0 .. $eventbox->get_screen->get_n_monitors-1) {
1) This causes problems...
