Offline version is extremely slow

Since November 2024 our offline system is very slow, sometimes freezing. All the other programs on the computer are running well, only Manager has a problem. We use a capacity of 3 MB within the system.
Any solutions?

That still sounds a problem with your system. As a new user please familiarize yourself with FAQ - Manager Forum because when posting you must at least provide:

… If your question relates to an apparent software problem (rather than an accounting topic), tell us your operating system (including the version), Manager edition (desktop, server, or cloud)…

and

So if you encounter a problem with the desktop or server editions, update Manager , even if you recently did. (The cloud edition is always up to date.) You can check the latest version at https://www.manager.io/desktop/download/ .

To help you further

  1. Is your business data saved on your computer or on an external drive or in the cloud?
  2. So after ensuring that you have the latest Manager version installed (version number at the very bottom of each business page) create a backup of the Business file and import as a new business on another computer with the same Manager version and see if still slow.
