If you are using VS2005, it is safe to modify the Dispose method in the .Designer.cs file. Otherwise, you are right and may have an issue (it's been too long since I've used the earlier versions so I'm not 100% sure if they will overwrite the Dispose method when regenerating the designer generated code).

this.timer1.Tick += new EventHandler(timer1_Tick);
this.timer1.Tick -= timer1_Tick;
