Looks like the tag code is changed in this release as it does not allow me to enter similar tags...
pressing enter does not work if a similar tag has already been put in.
i am not sure what could be the problem in this. maybe they are designing it in a way that prevents mistakes in entering tags...
but this is a problem for me because i tend to put in tags which might be similar but totally different. for ex. apple, apple macbook, apple macbook pro.
here is a replicable situation:
put in APPLE MACBOOK PRO and then try to put in APPLE MACBOOK or APPLE .
it does not let me.
but it works if i put in APPLE first and then APPLE MACBOOK and APPLE MACBOOK PRO!
