I changed the "TIA designer.layout" filename so I could bring it back if necessary, and so Code::Blocks would not find it just as if it were deleted. This solved the crash problem. Thanks.
Now I am able to see only the xml code in the wxs file. I am hoping that after I get it to compile the "TIA designer.layout" file will be regenerated and I will be able to see it.
My problem now is that between launches of Code::Blocks the setting at: "Settings => Compiler => Selected compiler" is not remembered. It reverts to the top most selection in the list when newly launched. What can cause this?
P.S. (Off Topic) The designer is based on Chapter 18 of "Building Electro-Optical Systems: Making It All Work" by Philip C. D. Hobbs. The transistor physics is based on "Electronic Principles: Physics, Models, and Circuits" by Paul E. Gray, and Campbell L Searle. A major problem with this project is that there is not a way to calculate a transistor's base spreading resistance for any given operating point, and frequency, from the manufacturer's supplied specifications. So the program's noise calculations will not be accurate in regard to this contributing noise source.
