Possible Bug?: Can not turn off Layer. Current Layer not identified

(This issue relates to v5A854. Not sure if it affects v5A858 which I’ve not downloaded due to working off a mobile hotspot while traveling.)

In a drawing with eight layers and three sublayers, I encountered an unusual problem with layers. Unfortunately, I can not replicate it, but thought I’d share the following in case it’s at all useful to keep an eye on.

I renamed the default layer (sort of always wondered—is this a bad thing?) and added three sublayers. With another layer selected (not a sub-layer) I wanted to turn off the (renamed) default layer. However, I was unable to turn it off. After a dozen or so attempts at selecting different layers and trying to turn off the desired layer, I noticed that none of the radio buttons were lit to indicate which layer was selected.

Some more clicking around on the layer select buttons and the radio button finally came back. Then the default layer was able to be turned off.

I tried to replicate it…even though you couldn’t. Predictably, I couldn’t. Consider it “on the radar.” Thanks for noting this here.

Thanks. Will report any further issues related to this.
