We're using RH 9 (latest build) to generate our chm files.
One of the developers I work with has problems in Windows 8 (8.1 to be exact) opening up our chm help file by double-clicking on the chm and it gives a software crash. The curious thing is if he accesses the help from within our own software by pressing F1, the chm displays fine. He said the chms didn't used to do this and is wondering what could have changed. Any ideas? It's not just our help system that does this though. He reports that any help system he tries to open from within explorer crashes. To me it seems like some necessary component got uninstalled or removed in a windows update or something, but wondering if anyone has experienced this and if they know the fix.
