Hi all, first post, sorry it’s about a glitch!
I’m experiencing the same issue. If I click on the background and drag around to move the canvas it works fine, but if I click on an adornment and drag around I get the same behaviour as in the video above; the canvas makes an abrupt jump to some random place before I start dragging. Sometimes the jump is so abrupt that the item I clicked on to drag is positioned off-screen somewhere and I have to drag around randomly to try and find it again.
I’ve never used Contexts (never even heard of it, actually) but I do use BTT and BetterSnapTool. However, I’ve turned off automatic start and rebooted to make sure they’re both cleared out and the problem still happens.
My machine is a MBP 2017 15" with highest spec (except a 1TB drive instead of 2TB).
To finish on a more positive note, I’ve spent all weekend reading about Tinderbox and going through Mark’s aTbRef website and I’m pretty sure I’m going to love this product! Even though I’ve only been using Tinderbox for literally a minute before running into this issue I already know I’m going to purchase the software and love using it. (aTbRef has made the sale!)
/edit - here’s an example:
If I click on the background or on one of the notes and drag it’s ok, but if I click on the adornment and drag it goes wrong.
