I installed Delphi 5 on a computer that had Delphi 7 already installed. When I first ran Delphi 5, it asked if I wanted to change the debugger to ...Delphi5\Bin\Bordbg50.exe and I answered yes. Code insight doesn't work in Delphi 5. I check Editor properties which has all the items checked and Debugger Options has Integrated Debugging checked.
When I run D7 it asks me if I want to change the debugger to ...Delphi7\Bin\Bordbg70.exe and I answer yes. Now code insight doesn't work in D7 either. It was working fine prior to installing D5.
