问题
I am upgrading from Delphi 7 to Delphi 2009.
In an existing app, the code completion does nothing at all. If I start a new project, it works fine.
Any idea what is going on?

Finally found the solution to this one, took awhile.
Added "WinTypes=Windows;WinProcs=Windows;DbiTypes=BDE;DbiProcs=BDE;DbiErrs=BDE" to:
Project Options -> Delphi Compiler -> Unit aliases
There is a whole big reason why, but to tired to explain it.
