problem with brain vision events after upgrade to 2.0.10

John,

The default setting for PreRelease has changed from 0 to "(same as 
duration)".  IMO this is mostly a good thing, but it does create some 
havoc for those following the older habit.  EP2.0.10 also introduces 
Generate PreRun, which again is mostly a good thing but can create some 
havoc...  You might find some of this explained in the latest New 
Features Guide, the "Critical Timing" chapter of the latest User's 
Guide, and various Knowledge Base articles online.

Note that, when updating older experiment programs, EP2.0.10 mostly 
preserves the settings in the program rather than imposing the new 
defaults.  This may explain why older, converted programs still work, 
while newer ones built from scratch in EP2.0.10 do not.  Start by 
comparing the PreRelease values in your old (converted) files to those 
in your new ones.  Then consider that the old files in effect used a 
Generate PreRun of "BeforeObjectRun", and compare that behavior to the 
new default "TopOfProcedure".

Best regards,
