In the "US Imaging" tab there is a part to control the update timers in the bottom. These controls are buggy:

1. If disabling "Update Image Data Automatically" only the timers should be stopped, but the image is deleted and invalid after disabling. I would expect to still have a valid image, but visualization updates must be done manually.

2. If disabling the check boxes "Update 2D View" and/or "Update 3D View" nothing happens. You have to modify the spinboxes to get the new settings working.

3. The framerate counter is buggy. I think is was buggy for a while now, if fixing is too much effort we can also remove it.
