It seems a lot of people are having crashing issues and such. Here are a few things I do to make sure MQ runs ok.
1. Be in OLDUI... NewUI is very buggy although nice looking it will crash with or without MQ running.
2. Make sure no extra eqgame.exe processes are running when you look at taskmgr. All of you people that are using 9x something sorry haven't used a 9x OS is 3 years so I have no answer for you but, theoretically this should still apply.
3. Make sure you have the correct offsets. http://macroquest2.com/eqgame.ini
4. This should be expanded just this is what I can come up with off the top of my head in 30 seconds
