dos - linux and animator pro

Hello,

I am running Autodesk animator pro under xdosemu with free dos on
Redhat 8.0
All works great accept the graphic mouse in animator pro editor only
works in 1/4 of the graphic editor area.
I am usinf a USB mouse then I went to PS2 with no improvments.
I suspect that there is a syncronization issue. I run animator pro
in 1024x768 vesa mode. I have run it in other modes including 320x200 with the same problem. I am hoping you might have some idea what the problem might be

Thanks,

Mike
