Rebasing IDA Database requires rescanning in Class Informer afterwards

So if you run ClassInformer (CI). And rebase, you have to run it again?
Can you even rebase while the UI is up? Don't think I've ever tried it.

Or you talking about how it saves the data the first time it's run, and now you rebase and the data is no longer valid right?
I can see this case for sure.
I suppose a decent fix would be to store the base at the time the data was saved, then the next time the plugin is run compare the current to the stored base. Then show a message "Rebase detected", delete the old store, and not even ask to use the old one.

Yes, if you ran it once and then rebase, none of the Class Informer found functions will show anything anymore upon double clicking.

Here is a step-by-step on how to reproduce this:

1. Run Class Informer
2. Rebase your IDA Database
3. Try clicking on any function and it won't have an effect

And yeah you can rebase while the UI is up. Even if you closed it, then rebased, and then when it asks you if you want to use the old result: if you were to click on "Yes" then the same problem will appear.

If you are wondering why anybody would even rebase their IDB in the first place: I work with X64DBG and the files I am analyzing sometimes have a different starting address so in order to keep the IDB in sync, I need to rebase it.
