There are other mechanisms like timeouts and idle methods that let you do something like this w/o threads. In some cases this might be easier at the additional gain that it will probably be more portable. > However, the data is only updated if I move the mouse over the window or I > keep pressing Alt.

It is all documented here: http://www.fltk.org/doc-1.3/advanced.html Especially this: "From within a thread (other than the main thread) FLTK calls must be wrapped with calls to Fl::lock() and Fl::unlock()" ... may be important for you. And this, too: "FLTK supports multiple platforms, some of which allow only the main thread to handle system events and open or close windows. The safe thing to do is to adhere to the following rules for threads on all operating systems: ..." (see last paragraph at the link above). > More info: Dev-C++ in a Windows 7. Thanks, but the most important information is missing: Which FLTK version?
