Triggering issue

[Sharp-grass]

Im making a 007 map. Dont laugh b/c its coming along great. Exept for this one GIANT problem. 1 second into game, dialog box appears. with 4 buttons. then no matter wut buttton u choose, another dialog box appears w/ 2 buttons. If u choose the "load" button then it goes away, but if u choose "new" then a new dialog box appears. with several buttons (new character names) Here is my problem: When the 3rd box appears, maby 3 seconds after it appears, all the options disappear, and warcraft freezes up. But it only happens online. Like when i do it in single player, its fine. It happens to alot of other testing my map too. This happens 75% of the times i test my map. and its reaaaaly slowing my map making progress down. If you have a resolution, or dont fully understand the situation, plz reply!!!
