Re: The order of my Levels seems to be locked - Why?
Thanks all for your inputs. Sorry for slow reply but I got busy.

I am using V7.5 on windows 11 64bit. 16G of RAM.

I spent some time tonight and created a new file and copied all my level contents from the 'stuck' file to this new file. The new file seems to be behaving correctly, ie I can freely manipulate the levels up and down.
So it is looking like my original file is somehow corrupted and for now I am back up and running.
If I find some time I may dig a bit deeper into that old file, deleting layers etc to see if it comes right.

I am reminded that I have recently (months?) started getting SH3D crashes with symptom of CPU/fan ramping up but the UI stops responding and I have to kill the process. Thankfully SH3D does provide file recovery however I wondeer if one of those crashes has corrupted the file? (or vice-versa).

Note that I am using the levels feature for more than just as 'layers', in addition I am using levels to create 'versions' of a design. So I create a level and copy-paste the previous level contents and then edit the new 'level' [version] from there. Some of the plan levels can be quite busy but I do delete old/uneeded levels to avoid file size getting to out of hand. But probably I am just stretching my SH3D/PC system beyond it's limit.

Note also that the reason I might want to change the order of levels is because of strange (and annoying) artifacts* that I see in the plan view that happen with doors when they are positioned close to another wall in a level of lower order, even when that 'lower' level is tagged as not viewable.. Snapping is also affected in a simlarly way.
(*I would add an screenshot of the artifact if I knew how to add images in this editor!).
