Working with a project and CurvesTransformation, I had a real-time preview open and pressed something, but I don't know what, and the preview went full size in the workspace with no way to close or resize the image. The real-time preview controls on the left side are present, but the top (or bottom) "close preview" button is gone - the preview goes from the main PI tool bar to the bottom PI tool bar, and there is no way to resize it. I can select another image from the lower PI toolbar, but it is hidden behind the real-time preview.
I don't know what I did to cause this or if it is a "feature", but I have tried every method I can think of to close or resize the preview, but nothing has any affect on it.
