There was some problem with active sync and resco pocket viewer,
here is a copy of the fix from another thread, it is in a message from
ephex double, in this thread (second page):
http://www.aximsite.com/boards/showt...ghlight=rescoe:
I found this fix on the Microsoft site in their user forum:
1) Remove the file named "picViewSync.dat" (If you have it) in the windows
directory on the pocket PC
2) Perform a soft reset
3) Synchronize again
If you're nervous, as I was, about deleting a system file like this, cut/paste it into your temp folder rather than deleting it. I'm now fully synchronized for the first time in days. "
this was from the X5 thread, but it might work on the X50 too.
