I know there were some posts about this already and some resolve themselves.
This happends quite a lot and causes issues.
Here is how this goes.
Say I want to print something from the catalog, this means I cannot pre-position it in inkscape.
This opens in GF UI, but I am not printing on prograde but using my own material.
I run first cut but it is not cut all the way through. I want to run the same cut one more time without opening cover or changing any settings, or maybe just adjusting power or speed.
In fair amount of cases, the GF will get stuck in uploading/scanning your material dialog. With Cancel button grayed out. And there is no way to cancel out or wake it up. It will just sit there.
If I reload the page it will lose my positioning of the shapes and all the settings. There is no way to save the setings.
This happens few times a day for me.
I wish there was reset button that would reset the dialogs and try to reconnect but keep all the shapes and settings in GFUI.
