SUMMARY

Documentation for the "Grandfather" patience game states: 

"This game was introduced to Paul Olav Tvete, the original developer of KPatience, by his grandfather; it is named after this. No other patience games are known to implement this patience game variant." 

I am informing you of another patience app that has this variant. PySol Fan Club Edition at least from version 2.21.0 has this variant listed as "Tvete's Grandfather."

STEPS TO REPRODUCE
1. Open KPatience
2. Start a "Grandfather" Patience game
3.  From the menu bar, choose "Help...Help with Grandfather"

OBSERVED RESULT
The first paragraph has quoted text from above.

EXPECTED RESULT
As I have found another patience game that implements this variant and have informed you, this may be corrected in any way of your choosing.

ADDITIONAL INFORMATION
This bug is not at all urgent. It's just a minor nitpick that can be safely ignored until someone updating documentation has a moment of boredom and decides to fix it.
