Filename of an image

Peter,

No way I've found to turn off or manually do anything with the cache. I'm using LC 7.01 rc2 and when I moved to it is when this became a problem for me. 

It should only be a problem when the image name is unchanged. As the system can still find that name in the cache even though you deleted the physical file on the drive. 

The physical file needs to be removed and by putting a different file name or some interim junk in the filename reference allows the cache to release it's copy.

Thanks Rich.  I've temporarily been working round the issue by deleting the
image and creating a new one as you mentioned. Fortunately, there's only
one image with the filename in question.

I was hoping there'd be a more elegant solution than deleting and creating
a new image but maybe that's the way it is.  I guess I could create my
image file with a different name every time I create it.

Sounds like there should be a way to switch off image caching.
