Hello Mark,
thank you for quick response! I checked on different machines and with two different autodesk-accounts. Some of the computers still using Version 2.0.5519 (Helpmenu, Info). There all toolbars are visible, everything is fine, independent from autodesk account/login.
Another computer: After restoring a clean WIN 10/64 image (from january, by clonezilla) I installed Fusion360 from webstream: Tools are executable, but tool icons are NOT visible. One can find them by hoovering over the region, looking for the tooltips popping out. Again, this behaviour is independent from autodesk account/login. This new installation of Fusion360 is Version 2.0.5658.
So I went back to the "older" image computer to continue preparing the course. After logging on even on this computer now the icons vanished. Seems that in the last 15 minutes Fusion360 is updated - perhaps triggered by my login. I check Help>Info (tooltips popping out!) and Yeah, right: now it is Version 2.0.5658.
First experience was on a ThinkPad T480, WIN64 (Version 1803), GeForce MX 150, Version 398.36.
The other computers are both Lenovo Yoga Books, 720-15, WIN64 (Version 1803), GeForce GTX 1050, Version 385.54.
Are there other users complaining this issue?
Hope my notices may help and thank you for your efforts!
Regards, Philipp
