PCLOS KDE 2012 32 bit updated
It seems that whether I use the menu or the run command to start 'partition manager' it doesn't open right away or sometimes it seems - not at all.
Today I entered the root password when asked but it was 5 to 10 minutes before it opened. I had opened synaptic and thinking about installing gparted and uninstalling partition manager when suddenly it opened.
Does anyone have any ideas about why this might be happening?
Yes it is a KDE Partition Manager and I use it here.

I suspect a problem with kdesu/kdesud
Does this always happen?
How about after a reboot?
I have had a similar thing happen every now and again with other apps such as Synaptic ...... so I launch System Activity window (Ctrl, Esc) and type 'kdesu' into the entry box.
I then kill kdesud ..... it will restart if required ..... and any kdesu entries also.
Then try kpartition-manager again while watching the process window.
Also ensure the entry box for the root password is not being hidden by something else on screen.
