Having problems with applications in the Market to download, or stall during installation? There is a solution that could help, and we have detailed in the forums. It is not complicated, does not require root or any real hack, and we even focused on the method to make the correction stick if you do not do it every time an application wants to install on your SD card. It circles around the .android_secure folder on your SD card, which is up applications using the "install method SD Card" that comes with Froyo want and need to be.
Hit the forums and take a look, because even if you are not having problems now, you never know when they might arise. [Forums] Android Central
