Why programs aren't installed to the SD?

[jvg]

Hello

I have a P3300 with clean official HTC WM6 OS. Let's try to install, by example, Google Maps:

I select it to install to the /Expansión Card (not the main device). All right, the program will install in the main device.... :(

Same with lots (all?) programs... What is wrong? any hint?

All work right and the SD card is accessible without problems

Thanks in advance, ;)

Some programs cannot be installed on the storagecard, only on the internal memory.

sd access is much slower then mainmem
sd interface is turned off when the device is off
so program which need to keep running cant

sd interface is not instant on when the device wake
meaning that ringtones and notification sounds in general
will not be able to be places on the sd as when they are required
to play the device may not be able to access them
