All options settings reset to default mid-working - no crash

Rhino
1

Hi, Have had this happen twice across two different machines in the past few months, both times working with multiple files open and then suddenly I notice that my aliases stop working and my viewport settings have reset to default. Not sure what’s causing this.

Posted earlier about my view settings being reset, and this is kind of following suit. Not sure if they’re related but it’s very frustrating. A lesson in backing up my settings more often I guess.

Info below for the latest, on my laptop (less powerful than the PC this happened on earlier)

Hi Aramon -

I’m afraid that gives us extremely little to go on, and I can’t say I remember other reports of such behavior.

I see you posted the SystemInfo data at that time as well.
Something that I’d say is not “usual” is that the ClimateStudio plug-in is listed in both. Considering how little frequent this is happening on your system, it’s probably not feasible to run without that for, say, the next 6 months?

Same thing just happened here. Multiple files open (mix of 3dm and dwg files) and suddenly all imported aliases and display modes were gone. Fortunately had both saved and re imported them again quickly.

It happened again today. Just one Rhino file was open, changed V-ray material reflection value on 2 materials, minimized rhino window, tried to open a new rhino file session double clicking Rhino7 desktop icon, then I chose the wrong template file (Small Objects - millimeter), forced Rhino to close clicking close icon on splash screen and all personalized settings were gone (aliases, display modes). Tried to replicate but no luck. Could it be V-ray related bug?
