Help!

We're encountering a user interface issue with Sugar 4.5.0f. I've posted a bug about it but haven't gotten a response.

Has anybody else entered this problem? Were you able to fix it?

From Bug 11365:
From Compose Email, click 'Select' beside the To/Cc/Bcc field and Popup_picker for contacts comes up.
The first time, it's a multiselect list view as desired.
After entering any search parameters, the search view changes format and becomes single-select.

While trying to debug this, I notice that the behaviour changes due to Contacts/Popup.php being called with 'html=' the first time, but 'html=Email_picker' any subsequent time.

This is preventing us from doing any kind of useful search operation on contacts and using the results.
