FSDB does not support debugging of graphics programs. It just blindly assumes that the text screen is always visible. If you need to debug graphics, you will need to change FSDB to make it switch the screen into the text mode when it hits a breakpoint. > Whenever I run something that uses CWSDPMI, and then I enter Win 3.1 (no, > CWSDPMI is not resident at this time), I get a high-pitched sound and my > computer reboots (!!). Please post the complete details of your system configuration. It is very hard to make anything out of reports that don't say at least that much. Most users (me included) don't have these problems, so it must be dependent on some peculiarity of the system configuration. > Also, I tend to get kicked out of FSDB with a > register dump (not sure which error) quite often. Is this under Windows or in plain DOS? Can you describe the circumstances under which that happens, like any specific operation you do in your program?
