FYI: Direct save to a local thumbdrive will not release drive until Chrome is closed
This is likely something to do with Chromeium and per se NOT a SketchUp for Web issue.
If I save a model directly to a local USB thumbdrive, I cannot “Eject the drive” whilst ANY instances of Chrome are open (not just the one that has SketchUp for Web running.)
Windows 7 SP1 x64
Google Chrome 68.0.3440.84 (Official Build) x64
This is also a very old SanDisk Cruzer Micro, 256MB stick which I’ve noticed does not work as well as newer higher capacity flash drives do. It’s light does not go out after having been “ejected” as others do.
(Think I’ll reward myself for recent hard work and get a new high capacity flash drive.)
More than likely the workaround will be, save to local harddrive then afterward copy to the thumbdrive.
