Was that question for me?
A few months ago started having issues with the market. I was having trouble downloading, loading the app, just all around problems. I went online and discovered a lot of people were having these issues so i assumed the problem was with google. then recently ive been having problems with apps closing on their own WHILE i was using them. Not force closing, but just like when you press the "home" button to exit an app. finally, just to experiment, i disabled an app that i always have running call "startup auditor". its a task killer, but more powerful. its the ONLY app that allows you to kill stock apps and actually keep them closed WITHOUT having root access (obviously the goal being to free up RAM). Now when i set this app up i was careful to avoid disabling any apps that have the words "google or motoblur" in the title, but there are some apps that if killed have hidden damage. For example, if you kill the "Voicemails" app, you will lose your 3G connection for a short period of time until the app opens up again.
SO, because of all these problems I was experiencing, i disabled startup auditor, and boom! just like that everything (including the market) started working snappy and sharp.
In short, if you use task killers, BE CAUTIOUS. because even if you think you know what youre doing, a lot of these stock apps hold more value than what meets the eye.
hopefully this is your problem, because it has an easy solution
. if not, i wish you luck, because i know how frustrating it is!!
