remove of Mail aliases failed

[Brujo]

i run into this issue when i like to remove an alias from the Mail Account Section i got the following fatal execption

0: /usr/local/psa/admin/plib/UIPointerLegacy.php:45
UIPointerLegacy->importLegacy(string '23', boolean false)
1: /usr/local/psa/admin/plib/UIPointerLegacy.php:74
UIPointerLegacy->importLegacy(NULL null, boolean false)
2: /usr/local/psa/admin/plib/UIPointerLegacy.php:74
UIPointerLegacy->importLegacy()
3: /usr/local/psa/admin/plib/UIPointer.php:844
UIPointer::getCurrent()
4: /usr/local/psa/admin/plib/common_func.php3:3943
wizard_get()
5: /usr/local/psa/admin/plib/class.Form.php:214
Form::getUpdateButton(string 'Click to delete mail accounts.', string 'confirm_submit(); return false')
6: /usr/local/psa/admin/htdocs/domains/mail/mail_names_remove.php:158

to solve it i selected the Mailbox which keeps the alias and in that Menu i was able to remove the alias. I created this alias again and afterwards i was able to remove it also from Mailbox Level but not the "old" alias. This shows exactly that there is something broken / not updatet with all the Aliases after upgrade to Plesk 9. This also refers to the info@ issue at http://forum.swsoft.com/showthread.php?t=56998
