原来可以做托盘图标的程序，转为服务之后，运行起来右下角会有两个托盘图标 ( 积分: 50 )

各位朋友，小弟原来有一服务程序，可以实现变成托盘图标在右下角出现，但现在将这个程序注册成系统的一个服务后，虽然该服务可以启动，但右下角却出现了两个托盘图标，不知道代码哪一部分有问题，请各位朋友帮忙指出，多谢！！！（试过将Timer去掉和将Create多余的语句去掉都不成功）

服务有个属性，是否允许桌面交互，默认是不允许的。

加一句
FIconData.hIcon := Forms.Application.Icon.Handle;
试试看

这个主要是此时FORM实际未被创建，ICON资源未读入造成的，我也碰到过。后参考Borland/Delphi/Source/Vcl/ScktSrve.dpr解决
