Taxonomy Other is incompatible with Active Tags

Greetings!

Here's a pretty major (if not critical) bug:
Say you have 2 taxonomy vocabularies on the same node creation form. One vocabulary uses Active Tags module and the other uses Taxonomy Other.
Then choose "-Other-" and enter your term. Then in another form try to add a tag in Active Tags module. Result: as soon as autocomplete suggestions popup and you press the down key to cycle through them, the cursor starts to cycle through the "Other" form controlled by the Taxonomy Other.

Bummer... I don't know what to do now - both modules are very important to my node forms.
