Unwanted keyboard language switch when Firefox/Thunderbird is selected

Question

Here is a problem that I think I've had in the past, but I just can't recall how I resolved it, or find any references to it in the forum archives:
Recently I reconfigured the keyboard language input menu because I switched to a different keyboard; it now has U.S. Extended, Norwegian and a 3rd map that I've defined myself. I can mostly switch quite all right between these (and the one I've defined myself works, too), but I have one very annoying problem:
Whenever I select a Mozilla Firefox or Thunderbird window, the language setting switches to U.S. Extended (if a different one was selected.) That is, if I work in a different application with e.g. my custom map selected, then start Firefox, I notice that the flag icon changes and that I get the US layout. I can then switch back to a different one and work with the corresponding layout in Firefox. If, however, I raise another application's window, then go back to Firefox, I find that language is once again set to U.S. Extendended. The same thing happens with Thunderbird.
Any idea what is wrong?

I haven't read your code, but can make a guess at what's going wrong. Checkboxes do behave in a weird manner depending upon whether you have selected one or many.
Assuming this is the statement where you are generating the checkbox :
<input type="checkbox" name="checkBoxName" value="<%= someValue %>">
What you could do is read the checked checkBoxes in an array :
String[] values = request.getParameterValues("checkBoxName");
int sizeOfValues = values.length;
Then use the sizeOfValues to perform your delete action :
if (sizeOfValues==1)
     performDelete();
else
     for (int i=0; i<sizeOfValues(); i++)
          performDelete();
Hope this technique works.
