I didn't see a special forum for the Question Bank, so it's going here.
I am using both Chrome and IE8, Moodle 2.0.1+. Not sure which build exactly, but I can find out if it's necessary.
Assume I have created a new numerical quiz question, and I have selected "Only the numerical answer will be graded, Unit1" will be shown under "Units handling" in that question. I have also entered a unit into the box beside "Unit1" below.
Then, when I go back to edit the question later, it has correctly saved all of my information but it has NOT saved my radio button selection in the "Units handling" section, reverting to "Only the numerical answer will be graded, no units allowed." If I try to save changes without checking this area, it will revert to the same page and demand I remove my unit from the Unit1 box.
I have not checked to see if this behavior is the same with the other two options under "Units handling" nor have I checked to see if it's happening with the other numerical types of questions (calculated, etc).
