For the first time in over a decade of using FB I cannot open up my program
for coding because FB 3 is saying that "A resource fork could not be added
to this file. You are attempting to run from a lock disk or the file is
damaged." I looked at the Staz site for info on this but could not find any.

Can someone tell me how to correct this? This program is over 190,000 lines
of code and 200 include files.

Thanks,

Doug Stemen
