odbc driver failing. . .

hi all.  i have written in about illegal page faults when i try to add 
records to a particular table -- editing it seems fine.  well, i have 
narrowed down another "weird" problem with the same table.  i reported that 
when i open it directly in datasheet view, the odbc driver fails every 
time.  this is not my largest table at all -- this one is 14M and over 45k 
records -- my largest is 23M and over 90k records.  i can open every other 
table up in datasheet view (msaccess97 by the way) except the 14M one. here is the log file after i opened a few other
tablesand then finally 
 
the one that bombs -- does anyone have any ideas about what is going 
wrong??  a few suspects -- the table has a field defined as varchar(300) 
and another varchar(550) -- i have the odbc driver set to cache 1000 (at 
least in this log file -- it was 100 and still bombed!), maxvarchar=550, 
maxlongvarchar=15000.  but editing the table a record at a time -- or even 
pulling up a subset of records from the table works fine. . .

thanks for any suggestions!  jt
