Hi, is there any linux curses expert around here ?

I have myself a supposed-to-work curses code (sample from a website) that uses mouse but it does not seem to be able to capture mouse events. The code is as attached.

Pls try to compile it for me [gcc -o sample sample.c -lcurses] and see. What could be the problem. Is it machine dependent ? My machine is a normal IBM clone with PS/2 mouse. I don't think it causes the problem. Or, can anyone suggest other alternative to control mouse from text based program in linux, without extra installation.



thx. Muhazam
