This is a temporary fix for Jamba 0.4d (the version name is still 0.4d, but it is a changed addon!):
http://www.wow-multiboxing.com/files/Jamba.zip

Changes:
- changed TOC version so it doesn't get marked as an out-of-date macro
- diggla's temporary fix that hides the group invite popup as it should

[edit] Updated!
