When posting problem code, you should post a minimal, self-contained

create the problem with one record, which you could give, and one

I'll firmly back that sentiment. Fredric, if you cannot get the
following simple code events to work properly, then how do you think
you can get events working properly on something more complex?
## START CODE ARTISTRY ##

tk.Frame.__init__(self, master, **kw)
self.bind('<Enter>', self.evtMouseEnter)

self.bind('<Button-1>', self.evtButtonOneClick)

event.widget.config(bg='magenta')

event.widget.config(bg='SystemButtonFace')

event.widget.config(bg='green')

I copied and pasted this self-contained code into a 3.3 Idle edit window
and lightly edited for 3.x. Change 'Tkinter' to 'tkinter', remove
tkconstants import and prefix constants with 'tk.'. (The alternative:
change 'tkconstants' to 'tkinter.constants', but I prefer prefixes). It
runs as expected.
import tkinter as tk
class MyFrame(tk.Frame):
def __init__(self, master, **kw):
tk.Frame.__init__(self, master, **kw)
self.bind('<Enter>', self.evtMouseEnter)
self.bind('<Leave>', self.evtMouseLeave)
self.bind('<Button-1>', self.evtButtonOneClick)
def evtMouseEnter(self, event):
event.widget.config(bg='magenta')
def evtMouseLeave(self, event):
event.widget.config(bg='SystemButtonFace')
def evtButtonOneClick(self, event):
event.widget.config(bg='green')
if __name__ == '__main__':
root = tk.Tk()
for x in range(10):
f = MyFrame(root, height=20, bd=1, relief=tk.SOLID)
f.pack(fill=tk.X, expand=tk.YES, padx=5, pady=5)
root.mainloop()
Add details and data (maybe less than 10 records) until you get what you
want or recreate problem.
