Hi Sushant,
I've tried filling in all the fields before making my copy in SP2.0 but it the tab cached icon doesn't turn green.
it also behaves strangely in the copied flavour...for example...
there are 8 tabs. tab 1 and tab 4 have field validations.
If I click on tab 2,3,5,6,7 or 8 - it automatically loads tab 1. if I click on tab 4 - it stays on tab 4.
it also forgets that I've turned on tab-caching if I leave edit mode and go back in.
