...ank, and the window also doesn't want to close. I suspect that my R_ReadConsole routine is the problem. This routine waits for user input and returns this (which I thought it should). It seems that this causes the event loop that updates the windows to also be on hold. I did have a look at 'Rstd_ReadConsole' in 'src/unix/sys-std.c', but I can't figure out what exactly happens in this routine. How do I ensure that the windows keep being updated? Presently I am working under Linux. However, I also want to be able to run my code under windows, so I hope there is a cross-platform solutio...

So on Rstd_ReadConsole() the if (FD_ISSET(fileno(stdin), what)) statement always fails. I did FD_SET(fileno(stdin), what) manually to enable the console. What other inputs exist that could have problems here ? I only found fd_set used in the modules internet aqua and in tcltk and those all dont work on BeOS anyway. I...

I tried to submit this in R, but not sure if it worked. When running R as sudo, using ctrl-c dumps me to the command line. Hitting exit to exit the terminal window results in R taking 100% of resources. I am using R-2.1.0 on Fedora Core 3. Thanks. Manuel
