Can't zoom in large panoramas

[D Bourke]

Lightrooom Classic CC, latest update installed, Windows 10 Pro, i7-6700K, 24 GB RAM, geforce gtx 960 2 GB, 1900x1200 display

Panoramas of 5 images (6000x4000 pixels) or more won't allow me to zoom in.  The image justs shows the gray background.  In initial attempt to zoom, a blurry zoomed image appears while "loading" is happening, then turns gray.  Clicking on image returns to fit view.  Changing zoom level, e.g. to 1:4 does not change behavior.

Panoramas of 4 images or less seem to work fine.

Turning the GPU acceleration off does not change behavior.

This was happening before installing the latest update.

Can anyone solve this problem?

Thanks, David

Can you icrease the cache setting in your preferences? What is it set to now?

I changed the camera raw cache size from 5 GB to 8 GB and it fixed the problem.

Thank you so much,

David

Same. Stopped working from one day to another. Didn't changed anything. Just imported a new pano.
