Payoffs changing unexpectedly

[amandaccsantos]

The steps to reproduce it are as follows:

• Configure GTE to allow 7 decimal digits
• Save the following as a .xml file (I can't upload xml here). The game is zero-sum. Indeed, in the file, player2's payoffs are the negative of player1's:

<gte version="0.1">
  <gameDescription/>
  <display>
    <color player="1">#FF0000</color>
    <color player="2">#0000FF</color>
    <font>Times</font>
    <strokeWidth>1</strokeWidth>
    <cellVertPadding>5</cellVertPadding>
    <cellHorizPadding>5</cellHorizPadding>
  </display>
  <players>
    <player playerId="1">1</player>
    <player playerId="2">2</player>
  </players>

  </strategicForm>
</gte>

• Open that .xml file with GTE
• Observe the third column of player 2
• Now, click on decimal layout, then on 'general matrix'. Note that player2's payoff has changed.

Could this be 'confusing' the online solver?
