Default SD card saving corrupt files

Hi all,
I've looked everywhere for a solution to the following, but can't seem to find anything about it:

After flashing 5.2.19199 UC RTM, my camera saves corrupt jpgs to the SD card (Sandisk 8Gb) that I can't open. If I change the save location to main memory, the files are fine. Also, voice recording with notes is set to save to the SD card, but after recording, it freezes for awhile, and eventually dumps the recording to main memory. Also related, Opera and PIE downloads are set to save to SD, but they either won't save, or are corrupt when I access them.

I have formatted the card and it works fine in the PC USB reader. The apps I have saved to the SD will run, but there is an issue with saving new files to the card. Cab files WILL install to the SD.

Is there a setting or program I need to run/fix/add??

Thanks, this forum is an awesome resource!!
