I really like the options built into the warning added in version 2.9.0.0053.
Somebody had a real good idea.
However, while I was testing these new features I discovered something that might cause some confusion.
If you close the warning message by clicking the X in the upper right it not only closes the current message, but also suppresses ALL subsequent similar warning messages ON THAT COMPUTER for any presentation. The condition resets automatically after seven days, but in the meantime there is no way to manually view the warning messages again.
Thanks to Justin for helping me figure this out.
