FIRST

In MainWindow, when the ShowImages button is clicked, an image pane is added to
a question component. At this point, if the EditQuestion action is activated,
the image pane disappears but the button displayed corresponding to images is "HideImages"! Further, if the EditQuestionMode is exited, the HideImages button is what is still active even if there is no image pane displayed.

Next, when the ShowImages button is clicked and an image is selected for addition, the image pane's container for the image that reads
"Drag new image here" does not act as a receiver of the dropped image.
Basically, when a user drags and drops an image in there for the
very first time for a question, it doesn't work. Instead, a blue bar appears above the image pane and just below the "Prompt", which is able to receive the image and then displays it within the image pane! Subsequent additions to the image pane seem to work fine.

I noticed the above behavior consistently over multiple documents.
