Hi its my first time posting here, I'm fairly new in using virtual box and I'm having a problem with my guest linux which runs on a xubuntu 32bit. I have already installed the Guest additions and its been working perfectly fine when I last left my machine. But when I turned it on and used it again the guest is not able to capture the mouse so its just stuck there in the middle not being able to move when i hover in the virtual box. I am able to use the keyboard and I have tried using my other guests which works perfectly fine. I've tried reinstalling the guest additions again and again but the cursor is not yet able to move.
Is there a factor that the source of this problem is that whenever there is an update on the software I tend to update it at once?

Just to add.. My "Disable Mouse Integration" button is disabled so I am not able to click it.. but it shows that mouse integration is on.
