Yes, you can
Go to Settings -> Environment -> something I don't remember -> allow multiple instances.
This way you can start two c::b's and in the second one you can attach to the father process (Debug -> Attach to process menu)
I start the 2nd CB IDEs,then attach to the father process.
The watches window shows "no symbol table info available".
The debug command "Next line/Next instruction/Step into/Step out" work properly.
The debug command "Start/Continue/Run to cursor" will kill the process being attached and start a new program to trace.
It looks like something wrong with the debug command "Start/Continue/Run to cursor" , or do I miss anything?
