Web app resize window "sticks" to mouse

When students try and resize windows (e.g. between workspace & directions) the window adjustment bar “sticks” to the mouse and follows the mouse rather than resizing and holding. This happens on a few different student devices.

screencast here:

Anyone else experience this and figure out how to make it stop?

It could just be poor performance on your computer. It’s not happening for me.

Multiple devices though…

It looks like the bar only tracks the mouse’s position if it’s in a certain radius.


This happens to my students as well. I haven’t reported it before. The only solution I’ve found is to reload the page. Could be a browser issue, perhaps? I’m not sure.
