Chitose Invisible window?

This took a while to close when last I shut down my computer. Anyone know what it is?

I found this on Google, but I’m not sure if it applies to your situation:

It’s part of a Fujitsu driver update program. The drivers are for stuff like hotkeys and touchpad. If may have been in the middle of an update check when you shut it down. Nothing to worry about unless it keeps happening.

Thank you!!:cool:
