This has actually been going on for quite a while.

In the "Render to Audio File" dialog box, clicking on any spot in the gray area of the box (without touching the check box or description thereof), causes a box to get checked.

It's most annoying when the "One File Per Track" gets checked accidentally and you have to wait quite awhile before you can go back and actually do what you intended....

Again, just an annoyance.... But I hope, at some point, the developers can get around to correcting the issue...

Thanks!
