The, oh, third guy I talked to with Dell a couple weeks ago, as soon as we'd opened the communication and he was controlling my computer, asked if he could close down my programs, then asked if I wanted my Mahjong game saved. I said sure, close down the programs but no, don't bother saving the game. But he said "No, I save it anyway," and he did, and now every time I open Mahjong, which is much more often than I'm going to admit to, it asks me if I want to open my saved game.
The first time, I said sure, I'll open my saved game. I completed the puzzle, went on to other games, closed Mahjong at the end of the night and thought nothing more of it. The next time I opened the program, it asked if I'd like to open my saved game. I said sure, completed the puzzle, went on to other games, closed Mahjong at the end of the night and thought nothing more of it. The third time I opened the program, it asked me if I'd like to open my saved game and I said yes, then realized that I already knew this game—I had already won it twice. I went into the Help section, to see what it had to say about unsaving games, and here is where I came upon yet another mildly so but still irritating feature of Windows Vista: there is no way to unsave a game. There are instructions on saving games, which is distressingly easy it turns out, but nothing about making them go away once you have successfully completed them.
So from now on, evidently every time I open Mahjong, it will ask me if I want to open my saved game. I say no.
