Modal Frame title always loading....

Aditionally, I created a new webform with only one text field to see if the issue was with the old webform but the new one has the same problem
also, I´m not using Secure Pages so the solution in http://drupal.org/node/513336#comment-1816626 does not apply (I think)
Aditionally, I created a page with an anchor link to my webform and it displays ok (title displays ok but still loads menus on reload after submit)

I realised its not a matter of js as examples works ok. the problem here seems to be related to webform submit procedure. when I send the form without filling some mandatory field, the modal reloads ok (using modalframe-page.tpl.php) but when I submit the form correctly, then I get the problem, complete webform with thanks message and every region loads on the modal (bypassing modalframe-page.tpl.php).
Should I try to close the modal or do I search to change submit actions with hooks? I think that closing the modal as an inconvenience: user is not informed that he did the submit correctly.
What do You people think?
Ideas on any of the alternatives will save my week :)

thanks in advance

Ok, I keep working on this :D
A few days ago I solved the issue with the webforms by including a new module and including on a custom hook_form_alter() a call to modalframe's function to include child jscript.
Now Im still having and interesting issue with this. I created a custom content type and on a node of that content type, the modal doesn't work fine. it loads the webform but the title keeps with "loading..." and then, the modal doesn't work as espected. but When I create a node of History content type and use on that node the modal link, then I get a correctly loaded modal window.
Will I get some day some help line from anyone else? :(

thanks again

Ok, I went a little deeper:
Im still having this problem on some pages (specifically on node pages of 1 content type)
the error that firebug gives me is:
Permission denied to access property 'Drupal'
on line 21 of child.js
if (!self.isObject(parent.Drupal) || !self.isObject(parent.Drupal.modalFrame))

I saw other posts with this happening because of a problem related with secure pages but Im not using them.
Could someone pleace give me a sign of life :(
Im freaking out
:D

I discovered something else: the origin of the problem seems to be a conflict with subdomain module wich I'm using. It seems that rewrite function of subdomain makes some changes on the url so parent and child doesn't understand each other.
I will try to fix this
Ideas are welcome. markus: I would apreciate your suggestions :)
I will write here any progress
