Cool that you posted this right now, because I did use the processEvents 
and it did the job for the 'apt-get update' since that's a fairly quick 
process. But I have spent the last couple of hours reasearching other 
ways to do it for apt operations that takes conciderably more time. And 
for that a simple 'Pleae wait' message dosen't cut it since it will look 
like it has crashed. So I have played around with redirecting stdin/ 
stdou without getting much wiser... so far ;)

Interesting. Will toss it around for a bit and see what I can make of 
it... if anything. I'm still on very thin ice every time I try something 
new. But that's paty of the fun, right? :)
