@rp1231
Maybe first have a look at the WM_NCHITTEST value when pointing at the titlebar, using the Identify Window option in the Blacklist tab.
Probably the program does not respond properly as it seems it is redrawing itself everything.

This is the blacklist tab screenshot.

It is a SDL based program so it is blacklisted by default.
You can still try to modify the MMBLower blacklist and remove the *|SDL_app, entry but I am not sure that it will behave correctly:

In the [Blacklist] section

MMBLower=*|CASCADIA_HOSTING_WINDOW_CLASS,*|SDL_app,*|MozillaDialogClass
; List of windows for which the Titlebar action should not be performed.
; default is MS-WindowTerminal and all SDL programs.

The reason that SDL apps are blacklisted in this way is that I was unable to make DOSBox windows behave correctly with AltSnap. Your experience might vary with different configuration and with a different SDL based program.

Yes thanks,
That solved it.
There is one minor quirk ( A deadzone to the left of the minimize button) but it is largely very functional and usable for this particular window.

I will link this thread to the wiki

Does this still persist?
I only tested DOSBox 0.74 and couldn't notice anything unusual.
SDL apps are very common, I at least use almost a dozen, and not one behaves irregularly (I deleted the blacklist entry long ago).

Edit:
Tested DOSBox 0.78.1, the most recent one.
Couldn't notice different behaviour between title bar handling and general hotkey actions.

I do not which version I was using but it seems you are right. Also maybe AltSnap changed too. I guess I will remove it from the default list.
