I used it to install Opera and then installed Startup Manager. Opera installed and works OK, but Startup Manager must have goofed things up as when I try to open it up, it tells me that I have entered the wrong password and now when I try to use the Software Manager I get the wrong password message also. I have run an update and used gparted to look at my drives so my password is OK. I uninstalled Startup manager with an apt-get with help here.
What can I do to get the Software Manager working again.
