Due to a misbehaviour of addPItoST43 each USER element of the tagpack didn't work anymore with TYPO3 versions 4.3.+ because the PHP classes were not properly included.
Please update your extensions as soon as possible to reactivate frontend rendering of tagpack based elements in 4.3.+!
For users of a "mini workflow" who are tagging lots of hidden elements that will be made visible by another editor after proofreading this bug means *the complete loss of any tag after unhidin*g. Setting/unsetting the checkbox in the usual backendform while editing the record doesn't trigger the bug, since commands are used for clickmenu items and icons only.
This bug has been introduced with version 0.6.0 and has been recently discovered by a client. Version 0.11.0 is taking care of the usual commands again.
