Reloading Lightroom's Preview
Core Elements 2 engines support manual reload of the page preview, meaning that to see changes made to configuration options, users must trigger a reload of the preview manually. Lightroom will not do it for you. There are several ways to accomplish this.
Go through the menu
Use the keyboard shortcut
On LR/Mac, press CMD-R to incite a reload.
On LR/Win, press CTRL-R to force reload.
BUG ALERT
Lightroom 3.x for Windows includes a reload bug which prevents the above reload methods from working. Selecting “Reload” from the menu or using the CTRL-R shortcut will cause the PC to produce an audible 'click', but will not reload the preview. Adobe has been notified of this bug, and we await repair.
As a workaround, we provide the following method of reloading your page …
Click the Reload notice
In the bottom-right corner of the preview, CE2 engines provide this friendly reminder of how to refresh the preview with changes. Clicking directly on this notice will trigger a page reload using Javascript.
Until Adobe fixes the reload bug, LR/Win users should use this method of reloading their page.
