Hello Mauro
I don't have the answer to it. I remember I used to have the same problem but I don't know when it got fixed.
Right now on a ArcaOS 5.1 (BIOS) under VirtualBox 7-0-12 (Windows 10 Host) I'm using this mouse driver and it is working fine:
- 1-31-20 3:06a 25,774 227 a--r VBoxMouse.sys
But I also don't know if the issue is the mouse or the video driver.
Mauro:
1) can you post your version of VBoxMouse.sys ?
2) Are you using Valery's latest version -
ftp://osfree.org/upload/vbox/additions/VBoxAdditions-os2-x86-5.0.51.r218.zip (2020-01-31)
3) What are you using for video driver? I was told long ago that with the GRADD that came on the addons was good enough. Panorama or SNAP didn't give much on the VM (as I was told)
Other general comments:
I'm using Valery Sedletski's "vbox
sf.ifs" (notice the slight change of name between "vbox
sf.ifs" and "vbox
fs.ifs") because it offers WPS share folder usage.
I recommended Valery to also try to get his VBoxAdditions version up to Oracle's available public source code, just to see if he can grab the good things about the latest version and see if there is something interesting there. But I guess he has not a lot of free time to work on it these days.
I think also asked in the VirtualBox Bugtracker to see if Valery's source code can also be used to improve GUI implementation of the "Share folder" with the host. But I can not find the evidence, maybe I dreamt it.
Maybe the only thing missing on VirtualBox guest addons is the "drag and drop" file sharing functionality, which will be also a nice to have.
Regards
