TOPIC: Conditional fields are very slow - need loading-indicator

Hi,

at first I would like to say "thank you" for this great extension!
I use Version 2.7.9 with Joomla 1.7.2.
I have a registration form with about 40 fields. Some of them are conditional fields - some are even nested conditional fields.
When the user changes one of the conditions the recreation of the form takes very long.
I don't think that this is a problem with the webserver or my internet connection. And I tried it with FireFox and IE.
It is Always very slow.
It takes up to 10 seconds to recreate the form.
This is too slow and some users might not understand what is happening.
Is there a way to speed this up?
Or is there a way to show a "loading-indicator" while the form is recreated?

Thank you very much!

Best Regards
Arno
