We are running 17.2.1 are you saying there is a newer 17.2.1?
I am still experiencing this to some degree. I developed the habit of repeatedly pressing the esc key to stop the update or loading of data. I started doing this as GM would not offer any information after the ESC press to let me know if the data had stopped or was going to continue to load. I am not a patient man... It never used to crash on me doing that. Since a few releases of v17 ago, and up to 17.2.4 from Aug 5th, it is still crashing if I repeatedly press the escape. It's pretty repeatable for me when loading World Images data and pressing the ESC repeatedly during refresh.

This linked to a 17.2.2 from July, which did not have the crash. The versioning seems very unusual. Short story, reverting back the this version fixes the bug. I don't know about V18 as I haven't upgraded yet.
