We had a similar discussion before and all we can say is that when you run dosbox natively mouse works fine. Not much one can do if you run an emulator inside a virtual machine. It's bound to be troublesome.

And why are you running dosbox in a VM on Windows 7?

You already provided all the information YOU need.

Sorry, I had looked around, and couldn't find anything about this.

To test compatibility with other systems. -- Specifically, testing multi-player across OS environments.

My point is not simply to run the program, but rather to verify if it will work in other OS environments.

Anyways, I guess I can refine this to:
If I get to the point where the game runs through dosbox inside virtual machine, but mouse is locked on edges, does this mean it will work fine if I were to run it through dosbox directly on a machine with whatever OS the virtual machine was emulating?

No but you can most likely say if it works ok in one OS with a certain version of Dosbox chances are it works the same in a different OS with the same dosbox version.
