Pocket Internet Explorer has started shutting down on its own as I am browsing some web pages. Its done it on Google Mobile, Orb DVR and others. Its done it while I've had other programs running and also when its the only program running after a soft reset. I've had the phone for 2 weeks and it didn't seem like it was doing this before a couple of days ago. I just did a hard reset today, and its still doing it. The only thing I can think of is that I have used Tweaks 2k2 to set the Temp file storage location as my Storage Card.

Any ideas?

You answered your own question dhenig. Just move the temp file back and you should be set.

this is a known issue caused by moving the temp files location to the storage card. move it back to the device and this problem will be fixed.

yup like said, you cant store your temp files on the SD
