Have tried to delete keys with the latest Flirc 1.2.0 and firmware v.2.2, the problem is still there. Have also cleared the configuration and started from scratch to see if it made any difference but no. Deleting a key results i a different key deleted, this is NOT a ghost key problem, isn't there anyone else experiencing this? Seems like the software somehow confuses the "index" of stored keys and the index of the key that should get deleted.
