eViewer no longer fully working

I have been using eViewer on and off for years. I recently opened a file I have opened many times before and can not rotate it. I can not zoom in or out and though i can explode the image I can no longer select any of the components to move them.  Anyone know what has changed? I am running windows 11 and have installed the latest version of eViewer with no change.

I did a quick search to see if anyone else has asked this, but did not see anything. Aplogies if this has been answered already.
