I have been using ubunut 8.4 for some time now and haven't had any major concerns, except for the fact that sometimes when I walk away from my laptop for a while and come back to use it and I have a couple of applications up on a couple of desktops, and I try to open another app (any) it will open a black window with min,max and close in the top right corner. It is like it is trying to open that application, but there is an error (?!?!?) The problem won't fix itself until I shut down the computer and restart it, but then it can happen again after it sits for a while... what could be causing this?
Also, on my desktop I went to www.starfall.com
for my son and the sound wasn't working for the website, but just that one. ??? It works with other websites and other applications, but not this one? The sound works on my laptop... maybe something to do with my firefox settings? I have tried and tried to tweek these, but to no avail. Suggestions?
