RE: [Foxgui-users]FOX work here?

MJester,

This case is usually handled by using multiple execution threads.

[Threads are little bit like mini-programs within a single process.
 Instead of running one program for the GUI, and another to crunch 
 the numbers, you would use the main thread to display the GUI, 
 and create a "worker" thread for your calculations. Since 
 the threads of a same process share their memory space, communication
 is very easy (global variables, ...).]

FOX, as a GUI library, has no direct threading support. But you can use
it in conjunction with the omniThread library (LGPL license), which 
comes as a separate module with the OmniORB2 library.
