Eclipse RCP开发中出现的No more callbacks 异常信息

目前发现客户端使用时总是偶尔会出现org.eclipse.swt.SWTError: No more callbacks的异常，界面不能响应任何事件.哪位朋友遇到过同样的问题吗？

做了几年的Eclipse，也没有见到过这种情况
1、把异常堆栈贴出来
2、看一下当前系统的UI句柄数

怎么查看UI的句柄数？

把任务管理器打开
在查看->选择列菜单中 将 句柄计数 加上
如果你的句柄太多，有可能是你的Font或者Image,Color没有释放

更多的可能是你的DLL有问题
你的版本是多少

因为没有你的源代码，所以只能猜了

我刚看了我的swt的版本为org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar

用过sleak做内存泄漏分析测试吗？ 我在我的eclipse上用不起来

我发现我打开一个视图的时候句柄数和GDI增加了，关闭此视图句柄数却没有相应的减少GDI会自动减少。
是我的dispose方法没起作用吗？视图里没用到font color Image 对象

我准备把程序放在3.3上面在试试
