SD Card decreases Program Memory!

[PolloLoco]

If IRC, it's one of the cache settings. Maybe glyphcache? Hopefully someone else will remember and tell you if it can be done on the Touch Pro - I used to tweak it on the 6700.

The problem is that if you do manage to reduce that value - your memory card access speed will diminish significantly. On my 6700, it often made the difference in being able to run certain programs off my memory card at all.
