Hey acenyc! Welcome to this site! You'll like it! Marty and the other experts on this site are the best! I joined for the same reason that you did! I had a total blind spot and got fed up and this site helped me.
Code:

 +----------------+-----------+----------------+
 | 4   9    6     | 7  2  3   | 1    58   58   |
 | 7   1258 1258  | 4  58 18  | 39   39   6    |
 | 38  1358 158   | 56 9  168 | 7    2    4    |
 +----------------+-----------+----------------+
 | 368 348  89    | 1  7  2   | 4568 568  589  |
 | 5   124  127   | 8  6  9   | 24   17   3    |
 | 68  128  12789 | 3  4  5   | 268  1678 1289 |
 +----------------+-----------+----------------+
 | 9   6    4     | 25 58 7   | 238  138  128  |
 | 1   58   58    | 26 3  4   | 269  69   7    |
 | 2   7    3     | 9  1  68  | 568  4    58   |
 +----------------+-----------+----------------+

Look for a naked pair down each column.
If you still don't see it, highlight the box below:

You can continue with the naked 58 pair in column 9!
