unstadered behavior in save table changes dialog

Hi there

This happened with me before but i really did not pay attention that time thought it was personal unconventional way of doing things

what really happens

loop
1- i modify a table structure (i deleted a varchar col)
2- i click another table label from the tree to perform the same action
3- a dialog appears indication changes were not saved what do you like to do
4- i click save
5- either another table is loaded in front of me or the application creches asking me to either close application or continue i click close
end loop;
