I have an issue that I have not been able to figure out, not sure if anyone else has seen this or not.
Some times when I download a program, or and update from the market, it will download, then do nothing, no notification that it failed, or was downloaded, but I watched it hit 100%. When I go to re-download it, it will show 2 files downloading and start over. If I leave the market, then pull down the drop down and touch the market download notification, if I had 1 program, it will become 2, if I had 2, it will become 4, etc...
I think its trying to download them all because the percentage done changes, and I can't cancel them. If I cancel them, the 'ghost' downloads wont stop, they just download then not install.
I have unlimited data on my phone so thats not an issue, more of an annoyance.
