Using WP X6 I cannot insert jpg images (or any other kind). I get the "conversion in progress"" message but nothing happens. Any help appreciated.
It is rare but not unknown for a PC glitch to cause big problems to WP and, indeed, other programs. Some years ago, that happened to my Presentations. I never sorted that issue. My WPX9 is now similarly affected. The only workaround I found, for both malfunctions, was to create another user and install the program as that user. That is very inconvenient, but it works, and it shows that a glitch had indeed affected either the files or the registry data related to the user.
Does this happen if you try to insert a *.jpg into a new, empty WP document?
