Bug: Subscribe by Email 1.0.4 breaks wysiwyg hyper-link button

Hi Guys,

I'm seeing the new version of "subscribe by email" break the functionality of my post editor hyper-link insertion button.

WPMU 3.1.1
Subscribe by Email 1.0.4
New Blog Templates 1.2.3

Subscribe by email plugin is by default activated across all sites (via the New Blog Template)

Notes:

Blogs created using New Blog Templates prior to upgrading of the Subscribe by Email plugin allow for hyperlink creation in the WYSIWYG with no problem.

Reproduce:
Update to Subscribe by Email 1.0.4
Create blog using New Blog Templates
WYSIWYG editor on new blogs will not allow hyperlink insertion using the hyperlink button on the editor.

Fix:
Disable Subscrbie by Email 1.0.4

Guys, let me know if this is something wonky with my setup or if this is a real bug. I would like to continue using the subscribe by email plugin.

Tim
