Can´t switch to Actual size preview after Saving a render in FF 2.011

Hello,

I have seen something curious:

When I load an image, sel ect a filter and have the "reduced preview" activated and the effect is applied,I go to "save as" and save that image, and then Filter Forge begins to render the image to save it.

The problem is that when it finishes rendering and saving, I want to go to inmediately to "Actual Size" preview to see the final result of the render, but I can´t go to "Actual Size" preview without making FF delete the already rendered image and begins to render it again fr om zero !!

I did not touch anything that would change the image, none of the settings or presets.

Please, Why FF delete the already rendered image ? Why it needs to render it again when it has already been rendered before for saving the image ? Is any technical problem or reason that FF can´t use the already rendered image for using it in the Actual Size Preview ?

IF YOU CHOOSE ACTUAL SIZE PREVIEW FR OM THE BEGINNING BEFORE RENDERING IT WORKS RIGHT

When I load an image, select a filter and I go to the "Actual Size" preview to see it in real size, and begins to render it. When it finishes making the whole image, you can go to the "save as" and save that render instantly and Filter Forge does not have to render it again for saving as it is already rendered.

You can use then the zoom to view all the parts of the image.

If you choose then the "reduced" preview it deletes the render also and you can´t go back to it if you then choose again "Actual Size" because it needs to render it again.

Please, why FF can´t keep the rendered image stored somewhere AFTER it has already been rendered once ?

Some technical reasons why FF can´t do it ?

It would be good to keep it in both cases, and you could switch between one and another if you want to
