No, that does not work either.
I also tried 'true' and 'checked' but to no avail...
The weird thing is, FF2 even behaves that way after I reload the page.
Like this:
1. I click on the link, all checkboxes become checked
2. I uncheck two of them
3. I click the link again, nothing happens, the two are still
unchecked
4. I reload the page (F5 or click on reload), all checkboxes become
unchecked
5. I click the link, all checkboxes EXCEPT the two I unchecked before
become checked
Seems like FF2 saves the state of these two checkboxes in some way.
To make it EVEN weirder (at least to me), if I don't reload the page
by F5 or a click on the Reload button in step 4, but click in the
command line and on Enter, without changing the URL, ALL the
checkboxes become checked if I click on the link again...
Could somebody test this behavior with FF2 WinXP? Perhaps it's one of
my extensions or something else.
Also, a test with another browser/OS other than IE7 or FF2 on WinXP
would be nice.
