Today, I have a tip for all users of the wonderfully simple and lightweight instant messenger “Miranda”. Sometimes the problem occurs that, when starting a conversation, the complete history of that contact will load and appear in the chat window. One may not even realize it at the beginning – I myself didn’t notice it for a long time -, until the history becomes so long that opening the chat window takes several seconds and makes the machine rattle.
For such and similar problems, there is a simple solution: In the installation directory of Miranda, there is a file named dbtool.exe. You can execute it after exiting Miranda. As a precaution, you can check “Create backup” on the first selection window. In the next window, check “Mark all read events” and let the tool do its work. Now the window should be empty again when starting a chat.
