I have some issues in my Ubuntu 15.04. It seems to be worse than the previous version. Start-up takes much longer time now than before ... looks like three to five minutes. When I put it in 'Suspend' mode, my PC woke up by itself even thou I didn't touch either mouse or keyboard. This is not like in the previous version. I installed DropBox straight from Ubuntu Software Centre. When I clicked on the tiny 'DropBox' icon on the top far right side, all icons on the screen disappeared. The Dropbox box opened up okay. I opened up one of pictures and it was okay. But when I clicked on 'close', 'reduce' or 'full screen' icon at the upper corner left side, my PC froze up. When I held down 'Ctrl' and 'alt' keys and hit 'delete' key, the PC resumed working ok, but icons were still absent from the screen. So I had to shut it down to re-start it again. Is these problems because of the incompatibility of my PC to Ubuntu? English is my 2nd language and I am not good at understanding English and I am still confused at how to reply to comments that come up in forums. It seems that I am being ignored in my previous comments that I put in the forums or did I misplaced them? ---------------------------------------------------------------- This message was sent using Distributel Webmail.
