I have a very large Tk GUI (7000 lines long), and in general, it works very well indeed.

However, occasionally, I get a load of errors reported to the invocation shell:

Tk::Error: Failed to AUTOLOAD 'Tk::Widget::EnterFocus' at /eda/dm/home/mili/scripts/perl/run.tk.pl line 264

(where line 264 is the invocation of MainLoop()

This error occurs randomly, and after many features of my GUI have been working just fine.

One example of when this error message occurs is simply when the mouse moves into the GUI (I have focus-follows-mouse ... so simply moving the mouse into the GUI window causes this EnterFocus error.)

That is, the program is working fine for many days/weeks, and then all of sudden, for no apparent reason, when the mouse moves into that window, I get the EnterFocus error.

Any thoughts on what might be causing this EnterFocus issue?

Thank you for any thoughts you have.
