[SD-User] SD problem

[IanSDavies at aol.com]

Just installed V15 after using V14 for a long time. Dipping into the SAC  
test all went well until QSO 32 when the F keys refused to function but  
otherwise could continue with rig control and winkey. However access  to the COM 
ports then became locked. Tried restarting the program and  PC  three times 
and the same problem occurs  after one or two  more QSOs  I have to restart 
the computer to clear the problem in order to  switch to another program 
using the COM ports. Have also reloaded the  program with the same outcome.
 
As the problem started just after 30  QSOs I suspect the SD key could  be 
involved.
 
Any help on this one?
 
Would like to do a comparative check with V14 but couldn't find it in  the 
archive.
