AutoCAD .NET :: Block Created And Inserted Shows Text Entities At Origin

I've written a method that creates a block definition and inserts one instance the newly created block definition.  The block is comprised exclusively of lines and text entities.  When the method is completed, all entities appear correctly on my machine.

However, when other users try to run the routine on their machines, the lines appear correctly but the text entities all appear positioned at the block insertion's origen.  And the other users must manually regen the drawing after the command is run to trigger the text entities to move (or appear to move) into their proper location.

 Though it wasn't necessary on my machine, I tried adding the following line as the last instruction in my command-method:

 _drawing.Editor.Regen();

 But even that last line's programmatically-triggered regen didn't solve the text location issue for my users.  They still have to manually regen.

I also ensured that all (or most) of a test user's system variables were set to the same values that I use (via Express Tools export & import).  But that didn't work either.
