4.2 - Checkbox : When onClick registered for, MRU not firing (demo incl)

Question

*** Hopefully this isn't a rehash, I've searched around but haven't found information on it. ***
I have a wizard created tabular report with a Checkbox (Y/NULL) column. The wizard also created the MRU and MRD.
In the page header, I've added the following Javascript function:
function testme(pThis){}
In the column attributes for my "Simple Checkbox", I added the follow to "Element Attributes":
onClick="testme(this);"
With this in place, when I click/unclick the checkbox and submit for a save using the MDU, the changed state of the checkbox is not saved to the database. Also, any new records (via new row) are added with a NULL for the checkbox field regardless of what is selected during creation.
If I change "Element Attributes" to:
onChange="testme(this);"
Then the MDU works just fine. Only reason I'm worried about this is that I understand onChange can be problematic on certain IE versions.
Thanks,
Scott

Howdy Howard (and others) -
I was hoping someone would have an answer without generating an example, but I hi-jacked the demo and came up with one:

Recreate Problem: Change the checkbox value of an item under OnChange and OnClick and press "Submit", only OnChange items actually change.
On this report, the two columns "OnChange" and "OnClick" are the focus. They are both simple check boxes and basically have the same settings. They both call an empty javascript function "test_me(this)" when clicked. Difference is, the MRU works for the "OnChange" column, updates are applied. You can change the "Onclick" column and submit all you want and it does nothing.
If you remove the event for OnClick="test_me(this);" from the "OnClick" column, the submit/updates work just fine.
(If anyone changes the demo, please return to prior state for others to examine)
