Using mouse with dosbox in windows?

Sorry if this seems like a dumb questions, but I have tried everything I could think of to get my mouse working as a mouse when playing old point and click games in dosbox core. It just does nothing, even if I toggle mouse capture or put Retroarch in fullscreen. Mouse is enabled in config, works in the retroarch menu but when I open a game in dosbox, it stops working. Some games even say only a controller is connected. What am I missing? Is mouse not supported?

Thank you.

It’s working for me in many games. See if there is a setup.exe to activate it or something.
