You better do so. Unfortunately I don’t think we are able to properly help you with that. Though there might be people around having had this issue too. Not sure. But you’re definitely better off posting this virtualbox-specific problem in their forums.
Upgrading to the latest git version solved my image resizing problems but now I’m having another issue.
Can you please be more specific to which version you upgraded. Latest git can mean different things. Is it dev-branch or working. As well post the version numbers you see in the blue cloud on the web UI.
When you schedule a tast for a client you don’t do multicast for all 27 labp PCs, right? Scheduling for xxx-002 for example, what do you see in “Active Tasks” on the web UI? Does it say 001 or 002? Something seems odd here.
