Does this analysis sound right? What can I do prevent the ever-increasing memory footprint?

It sounds plausible, and if that is indeed the cause of the leak, you would patch http://cpansearch.perl.org/src/TEVERETT/Win32-CtrlGUI-0.30/Win32/CtrlGUI/Window.pm so it doesn't leak

But, your analysis could be wrong. Given this piece of your code 

exit unless defined $coord;
...
$check = $mw->after(10, \&CheckIDE)

[download]
it could easily be $check or $ide or CheckIDE leaking.

So the bug could be with your code, your version of perl, Win32::Setupsup, Win32::CtrlGUI, Tk::after, or two or more of these things together.
