You're calling VFS routines from a different task than the UI task? I don't know that it is certified for use in anything other than the main thread: reentrant code generally isn't something that most of the 4.0 OS is designed for, and it could easily cause weird problems like the ones you mention. -David Fedor Palm, Inc. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
