Found a small bug in isolate and the filter box.
Open a new file draw a sphere and a circle
Open the filter dialog box
Close the filter dialog box
Select an object and use the isolate command
Notice that the filter opens up even though it was closed
Now it will open every time in a session unless you have disable checked in the filter dialog box,
I like to leave my filter choices checked then close the dialog and not disable it. that way I can open it again and my choices are still checked. While closing the filter essentially disables it but leaves your choices I like that. Also it should not open on it’s own unless you use the sub-d commands.
This seems to be an issue still. After the latest update I am seeing the selection filter pop up when running Isolate, Insert Edge, Slide Edge…possibly a few more. I’m using the floating selection filter dialogue box, and the behavior only happens after I’ve manually selected a selection filter option from the Sub-D menu bar, after which the pop up is persistent. Also, when the dialogue pops up there are no boxes ticked, but the sub-objects box in the lower right is greyed out.
