debugger problem

I'm using Rad Studio 10.2 - CBuilder. The first time I use the debugger it works ok. But if I try to run the app again i get the following message:

PAClient Error: E0009.Cannot create file (path). The process cannot access the file because it is being used by another process. 

I then have to kill the debugger process using the Task Manager.  Some time ago I ran across a fix for this on the internet.  It was an option in the project manager but I don't remember the option & have not been able to locate the fix again. Does anyone know what the option is?
