In Chromium/Linux
Never had this one before, but in the last few days, on 3-4 occasions, i have had a block pile up catastrophe hit my blocks editor. A click on a block or the background invokes the pasting of all the blocks on screen on top of the existing blocks. Another click does the same. on one occasion I saw that a click was pasting blocks from different projects in my project list as well!
Fortunately for me, my block counts have been low, and eventually, once I regained control (restart) I was able to delete the wrong blocks then carry on. (Yes I have regular backups too.)
Doesn’t seem to be any rhyme or reason to it, just happens…
I am running with two chromium profiles open for two different google accounts, but only one instance of AI2 running.
