Keywords - assigning and deleting is extremely buggy

Question

Hello,
i tried to use keywords in iPhoto and found it useless. Why?
There are many situations when you loose keywords or get keywords assigned you never did yourself. It specially happens when you try to delete one keyword frome some selected photos. Let's say you have an intelligent album open. You select some photos from which you want to delete one keyword. You select the keyword in question in the info panel and press BACKSPACE. Now all photos are gone from this album. If you look which keyword are left in the photos you will find, that _ALL_ the photos lost this keyword, even those which were not selected. And very often now they _ALL_ have another new keyword which you never assigned. This error I can produce on every computer and with any, also a new catalogue.
I also found, that if you assign a new keyword to some selected photos in a collection _ALL_ the photos of the collection have this keyword assigned, even those which definitely were not selected.
I also observed, that you need to delete a keyword at least two times from a single photo to delete it really from the photo.
And last but not least: I you open a collection/album and select all photos you will not be able to assign a keyword to thos pics. You first have to select one photo and then all photos to be able to do so.
I really wonder if anyone ever used keywords for more than trying and playing around...
As far as I can remember, these problem did not arise in former versions together with the plugin Keyword Manager from Bullstorm. Right?

Try adding and removing keywords from photos with the Keyword pane which is brought up with the Command+K keystroke combinatiion.
Select a photo and all assigned keywords will be dislayed in blue.  Click on those blue keywords you want to remove from a photo.  Move to the next photo and repeat.  You can also select multiple photos to batch add or remove keywords.
