Sharing stack via revonline

[Severin Swensen]

I shared a stack online via revonline and have trouble updating it to  
a new version.
I share it the first time and put in a description
Then I save it to my local drive.
Next time a load the stack from my local drive make some changes and  
click share this stack.
This opens the revonline viewer I click on my space and tried various  
alternatives but can not update the shared stack, short of deleting it  
and then adding it again.

Thanks
Severin
