Thank you for this module, but i have the following issue : any time i try to update from CCK Fieldgroup Tabs 6.x-1.x-dev (2008-Oct-01) to 6.x-1.0 (2009-Aug-19), i loose all my tabs.
Once, i got the tabs back after clearing caches, but from time to time i loose tabs and all infos in tabs is not displayed !
So i went back to CCK Fieldgroup Tabs 6.x-1.x-dev (2008-Oct-01) and it works.
D6.13, jQuery UI 6.x-1.3, Tabs (jQuery UI tabs) 6.x-1.2... all other modules uptodate.
Do others encounters the same issue ?
