There are sometimes problems with using SyncTeX to jump from the preview to the source window when certain packages are in use.
In these cases, if you try to double-click the preview or use the arrow buttons that sit on the divider bar between the source pane and the preview pane, an error message will be displayed:
Couldn't find the corresponding source file.
This is known to happen in documents using the TikZ shadows library.
If you see this error in a project where you're not using TikZ shadows, you can send us a support request and we can investigate further.
