[Can't select the rotation hoops]

In the General preferences, there's a checkbox that says "Restore window position on start". Uncheck that.

If that response was to me, thank you... that definitely stopped Cura from opening on external monitors regardless of wherein was closed but it didn't change the behavior that, when on an external monitor, the model and control handles for rotation, drag, scale etc are not clickable.  Clicking on the model in the "Object List" is the only way to select the model and none of the handles are draggable.  

All those issues go away when on the laptop (primary) screen.  I understand that I can just use this on my laptop, which is what I'm doing, but it seems like a bug that it doesnt work on external monitors.

[Can't select the rotation hoops]

Was there ever a resolution to this issue?  I'm on Cura 4.13 and had no issues last night using my laptop, mouse and laptop screen.  Today at work, I cannot select the model with the Left click, and none of the handles for rotation, movement, etc are selectable via mouse.  Searching for this issue lead me here.

 

However, when I dragged Cura off one of my external screens (third monitor on the left) to the laptop screen (first monitor on the right), all selections and the mouse button were working as expected. 

 

Seems to me, it only affected me when on my external monitors.  Perhaps cura has a hard time determining where the mouse is when it's not on the primary monitor.  

[Cura will not start Slicing (OpenVPN conflict)]

Hello,

I noticed a consistent and reproducible issue on my Mac running Cura 4.4.1

 

Whenever I am connected to an OpenVPN connection (how I sometimes connect to OctoPi/OctoPrint) Cura will not start the slicing process.

The following errors will show in the logs :

Now that I've determined that it is an OpenVPN connection causing the issue, I've been able to reliably work around it by disconnecting my VPN before slicing.  I was just curious if there was something I could do to get them to play nice together.

 

[Cura will not start slicing]

Does the slicing progress indicator change but show no progress?  Not sure about windows, but on a Mac, I had this issue that consistently occurred when connected to a an OpenVPN connection.  The log files showed that Cura was unable to connect to "Backend"
