I can't reproduce this effect... Can you post (on your website or somewhere) a compileable example of what you are doing that manifests this behaviour? Also, what platform are you on? What compilation tools are you using? One thing that occurs to me... Do you maybe have fltk-1.1 installed, in such a way that the compiler might be finding the 1.1 headers in preference to the 1.3 headers in some cases? If so, that would be *bad* as the headers have the same names and *similar* but different widget definitions... So code will often compile and link OK against the "wrong" headers but will segfault badly at runtime. Might be what you are seeing? If so, you'll need to segregate things a bit to keep it tidy!
