The thumbnail tray may appear to be missing files when a presentation viewer changes his or her browser display settings to allow for more visible screen space. All files are available, but the files are pushed out of the viewing area if the viewer has their browser zoomed out. This is not a bug in Wiredrive; it is a function of how Web browsers render the code per universal access settings.
How do I adjust my browser view settings?
The interface for reseting the zoom controls varies slightly from browsers to browser, but the basic process is the same for all platforms:
- Make sure your browser is the active window
- Select View > Zoom > Actual Size (or 100%)
- Mac users can also can press Command-0
- PC users can also Select > Page > Zoom > Actual Size (or 100%)
