Hi, We have an interesting issue: We downloaded an SDK kit that had several .CHM files (Help Files) and when placed in a my documents folder in Windows 7 that is set to sync with a network location with Sync Center it doesn't open correctly. However, if you copy the SDK package locally "not Sync'd" it works great. When we open the .CHM file from the Sync'd folder regardless of being offline or online it displays the TOC but in the windows where the information about each topic is giving us this message "Navigation to the webpage was canceled - What you can try - Retype the address" Does anyone have any ideas to why this is happending? Thank you.

Right-click on the CHM file and click Properties Click "Unblock" and click OK. Does that help? If not, you may have to adjust some security settings for the CHM file to display correctly from network.
