When I have an image open and select the Camera RAW filter (from the filter menu) everything is fine. I can see and access the entire workspace.
When my wife opens the Camera RAW filter the contents of the workspace (not just the image) is so large that she doesn't have access to all the controls of that filter. Using the fit menu at bottom left (circled in red) controls only the size of the image not that of the entire workspace.
Peter beat me to it; it is a screen resolution issue. Clicking where Peter has indicated should fix this issue, but that doesn't mean all the tools will be visible. If they are not, there should be a scroll bar on the right and she may have to scroll down to get access to all the tools.
Thank you! I always know that there are some gurus out there that can help us. It is funny just how differently my wife's Photoshop and Bridge look compared to mine. I am quite proud of her for her tenacity in learning these programs fairly late in life...
