Hi Rafael,
first and most important: I am perfectly happy now. Everything works as I find it to be optimal.
[quote user="Rafael"]According to your description, I am almost sure you hit the green bug button 
after you do modifications to your code, is that so?[/quote]
Correct.
[quote user="Rafael"]Instead, if you simply hit the hammer button 
after doing the code modifications, it will simply prompt you to reload the file.[/quote]
In the Debug perspective (is it called so?) this button was not available. I made it available, associated a short key to it (F12 instead of ctrl-B for a "single-finger action", there may arise an interference with another F12 association) and it works perfect.
BTW, when I started the CCS after a windows shut down, the recent perspective was not restored. Not so bad, not much to reconstruct. This time, as a precaution, I saved the current perspective.
I don't want to tell you my life story, but maybe you might understand me better when I tell you that I am not a professional software programmer. I have many years of experience with the 8051, but in Assembler only, I get along with Visual Basic for my own purposes, I even made a complex (at least for me) project in C on a 32 bit µC, but I always needed much help and assistance because I often did not understand what really was going on there.
To really learn to know a more modern, small µC I tried the ATMega, but the IDE on my PC drove me simply crazy. Something on my PC and its USB interface mostly inhibited to download code. So I stopped working with it. Ok, maybe later, with a new PC.
Then I tried PIC and came to the conclusion that it is a punishment to program PICs in Assembler. Moreover, the PIC I used was a lame duck. Ok, maybe later in C for small projects.
Next was MSP430. This is a much more complex µC, but well done and I liked it. The IDE turned out to be stable but even more complex than anything I learned to know before. Most items I find there don't mean anything to me. But with your help and a little guessing, searching and googling my little assembler microcosm works fine and I'm happy with it.
I'll keep the other tips you gave me in mind and have a closer look at them should I experience difficulties or problems that might fit to them.
Thanks a lot again
Uwe
