"Show result" button does nothing when 3D is enabled

After processing a 3D image with ANNA-PALM, I have the possibility to view it in 3D, as the "show result" switch appears. However, this switch does not update the 3D view. My guess is that this happens because the processing is only performed in 2D, so there is nothing to display in 3D. Thus, I find this switch a little bit misleading. Could it be removed/greyed when the 3D view is enabled?

Many thanks for this great code!

Locate the "show result" switch and the code handling the 3D view after ANNA-PALM processes an image. Confirm the behavior when processing is only 2D, then make the control unavailable or disabled while 3D view is enabled; done means it no longer misleadingly suggests that a 3D result can be displayed.
