More Virtualbox Problems

So, I’m running Fedora with Gnome. When I fire up Windows 10 in Virtualbox, the VB menu tabs appear at the bottom of the virtual machine, covering up the tray. Of I attempt to minimize it, it leaves the Windows window. When I reclick on it, the tabs are still there. If I try to close it, it freezes the host. I can switch workspaces, and windows, but I can’t do anything within them; clicking on links, or new tabs within a browser instance, does nothing. The cursor remains an arrow regardless of its location. The only way to fix it (that I’ve found so far) is to reboot, which is a PETA, because a lot of stuff has to be autoloaded each time.

Any ideas for troubleshooting?

[Saturday-afternoon update]

OK, I have discovered that I can unfreeze the host without having to reboot, by killing the VM process. So that will help. But it’s still not switching properly between full-screen and scaled modes. And I still have to modprobe the driver every time I reboot, or the machine won’t start.

Merging Lanes

You’re probably shifting out of your lane too soon.

Driving back from Yosemite on Thursday, Caltrans had shut down the right three (out of four) lanes on I-5 in Castaic. We lost one lane at a time, and the first merge was the slowest. Each next one sped things up, until we were all in a single lane, and moving at a reasonable speed. Part of the problem was that much of the traffic in the right lane was trucks (we were already in the left lane when the backup started). It added about twenty minutes to the trip time.
