Something has been bothering me when solving puzzles and I couldn't quite place what it was.

I don't have great mouse skills, often not quite clicking where I intended.  But behaviour I experience often felt a bit wrong even after taking that into account.  I had a couple of theories, but never bothered to test it more deeply.

My theories appear wrong (I thought that maybe shift pressed status wasn't being propagated reliably depending on where you click...).

But I did discover a clear discrepancy between standard and variations.

In standard no matter where you click, it will always make a mark, even the very centre of an intersection will take the 'closest' line and toggle its state.

In variations however, any click on an intersection is guaranteed to do nothing.

Beyond that, I'm even seeing dead space not on an intersection, not some consistent distance away from edges either.

I would think it would be better if variations was more consistent with standard and all clicks always cause some change. I wonder how easy this would be to fix?

I've made some changes and it should work like this now!

Deadspace is definitely fixed in general, thanks!

However clicking on intersections still seems to do nothing. I'm less concerned about this now that the fix for drag state management went in, but FYI anyway.

Actually yes, sorry I forgot to mention I found with the variations puzzles that clicking on one of the dots is perhaps a little too random as to which line gets affected, especially when there are lots of lines coming off a single dot - so you have to be a couple of pixels away to make it clear which one you want; for me, at least, it improves the accuracy of dragging.

Sounds reasonable to me.  Thanks again.
