I replicate your procedure and i got exactly the same behaviour, also to me it seems a bit strange as behaviour, altrough i have to admit: i start to be confusing !

I presume the entire mechanism need to be revisited ..
I don't think so, save is also involved, so it means that most part of the ghost/unghost "mechanism" in general need to be revisited, found a method to replicate any kind of strange behaviour unfortunately isn't easy nor convenient at this point, so including the bug already opened i will suggest you to ask for a general revisiting of the whole buttons functionalitieskas1e wrote:@all
I assume there is no needs to create new BZ for bad ghosting of undo/redo again ? I mean as it all about ghosting, once it will be fixed (the BZ which we already create) the other ones disappear as well imho.
Sound good, just in case you may also include the URL of this thread so the mantainer will able to read the entire discussionkas1e wrote:@samo
I just update the same BZ, and change name of it to "Undo/Redo buttons stop working after a bit of manipulations (few bugs in diffrent cases)", and made a 2 reples. One about first test case, another one is that last one from Amigo1, + add some notices about whole problems with that undo/redo. So, when work on fixes will starts, everything will be there in one place.
