The first time a class name is encountered by the compiler specifies which 
name the class will have in the interpreter, and how the interpreter will 
memorize it. 

And for Form objects, it implies the value of the Name property.

So the interpreter will take the name from the first loaded class that uses 
"FWorkCover" or any case variant. I guess this is "FWorkcover" in your case. 
Then this name will be used during the entire life of the program.
