Rise crashes when adding markers to a labeled graphic

Hi community,

I'm experiencing a problem with rise. I want to add a labeled graphic. The first two markers that appear automatically when adding a new labeled graphic work just fine.

However, when I want to add a third marker rise just...crashes? The whole browser window turns grey and it stops displaying the course name in the tab. When I close rise and just start it up again, rise asks me to take control from the currently working user (me).

My original picture is a .png. I've given it a try with a .jepg as well as a smaller image, since mine is fairly large, but I'm still experiencing the same problem.

I'm currently working with the trial version of rise.

Any tips are welcome!
