Re: import function

This is a tricky question to answer without the data file in
question.  I would certainly recommend sending this to Wolfram
Technical support (along with the problematic data file).

Remember though that Import[....,"Table"]  is a import format tht uses
a wide variety of heuristics to figure out what the contents of the
file is and then attempts to turn that file's data into the proper
formats and types.  If you have a much more strucured file, it may
make more predictable sense to use a more constrained import format--
rather than "Table"--to read in the file.


Hope that this helps,
