I opened an old project in version 6.80 and found I was not getting a list of methods and properties (what do we call that facility?) for a library object. A couple of hours and a lot of stripping down and I had a new file that worked and an old one that didn't despite being apparently identical in every respect. Resorting to a Hex Editor I finally noticed the difference in the data area of the source file. Type of libary object - CodepageFile Working project - Object1=cpf:CodepageFile Failing project - Object1=cpf:CodePageFile It looks like a case-sensitivity problem. Notice the uppercase "P", manually changing it to lower case in Notepad made it work.
