Great Problems (ok maybe not so great)

[JeffWorm]

When i played Worms a pop-up came up
so it minimized the game and it couldn't go back
to full screen and i couldn't control the game, please
help me. Thanks in advance.

what was the popup?

Do you have the latest update installed? The update at www.nanacide.com/wahelp is the latest, and enables the game to minimize, and therefore be restored later.

It can't normally do this.

There are some games, that can take a change to the desktop (with ALT+Tab or Ctrl+Esc), which is what happens when a pop-up appears, and still function normally. Other games can't.

The only way to avoid this problem is to avoid the pop-ups.
Firewalls, Anti-Virus-Programs etc. display such pop-ups, so you should turn them of or go into game-mode (ZoneAlarm has a special game-mode, where it doesn't ask the user to allow actions of the program, but simply accepts or denies everything).
Wireless Logitech-mice using set-point show a pop-up, when the batteries are low. So you should only play Worms with enough battery-power.
There are probably a lot of other programs, that show pop-ups, just try turning them off.
