Hello to everyone. I cannot view most of the titles in the help file of IDECAD in XP. I do all the updates on the OS periodically. But I was not successful in any way. I tried it on Win 7 RC version. I saw the Help titles and content, this time "WHAT IS THIS?" feature did not work. I finally tried it on Vista Ultimate from a friend of mine. I got the result. Does anyone have a similar problem or have any suggestions for a solution? Good work..
