Definitely, the behavior has to do with the 255 char limit - in this case, of .rowsource, when .rowsourcetype=1 (Value). In the case I had today, rowsource string was 299 bytes long, and it not only truncated it at 255, it also left out two rows and part of the one before, and at runtime matched any blank field to the last available row (below 255) - because the missing part was the 2nd column (the bound one), so the last .

The workaround is a bit of code to list one row at a time and stuff it into .aList array of the combo... something like this
