Hence the word "limited" does describe the effect and limitations. Many games do not support such an user.
I fixed a few by copying shortcuts to the user, then figuring out what permissions to what registry keys needed loosening, but that is all too generic an answer for some but without a specific name (and then it would have to be one I fixed recently) all that can be shared is the generic procedure.
As to manuals, I just dumped 40 pounds of manuals (mostly about Clipper and dBase programming) into the recycle bins today. I'm sure I have more if they are needed.
I am having a problem in that some programs installed while logged in as Administrator, do not show up as available to the Limited User account. As I recall there is some option relating to making new installs available to all users, but I had thought it was switched to allow all users access to my new installations. I have not had a problem previously with many, many other software installations in XP Home.
(I really long for the bygone day when manuals came with software. For recent computer users, a manual is a book which actually lists all commands, options, etc. They used to be sold with software. This is NOT an urban myth.)
