timeout on background task?

Hi,

i make good use of the "run task in background" feature when invoking my Fortran compiler.

This works very well except in one circumstance:

When my source file takes longer than about 10 minutes to compile, the logfile puts up a message saying that the task has completed, when in fact it is only 50% through the process.

Is there a way of changing the timeout?

It's not urgent, because I get an error status of 258 so now i know i have to wait before trying to use the compiled file but it was a bit misleading when it first happened!

TIA

K
