My English is not very well, so I had to use my mother tongue.
本人音乐播放器用的foobar2000，不是英文官方版本，而是foobar2000中文论坛ashin的汉化版。
自从小a升到7，我就打开了我一向不勾选的自动沙盒功能，打开foobar2000时，小a沙盒模块启动，十几秒后选择了下次正常启动，foobar2000安装路径于是也到了沙盒模块的排除路径里。
今天点了小a主界面右上角的设置里最下面的“疑难排解”，将设置恢复成默认设置重启，打开foobar2000不再弹出沙盒提示框，我疑惑地打开了沙盒设置界面，发现排除路径里空空如也。
我抱了试试看的心理在控制面板的卸载程序里选择了修复，修复界面上大概写着“所有设置恢复成默认”这么个意思，修复完成手动重启后再打开foobar2000又弹出了沙盒的提示框。
说了这么多，大概的意思就是假如有某一个程序运行时小a弹出沙盒提示框后选择了下次正常启动，而用了主界面的设置里的“疑难排解”恢复默认设置，下次运行该程序小a就不会弹出沙盒提示，虽然沙盒设置里面的排除路径已经没有了。 如果要使得它弹出，则要在卸载程序里修复小a。
为了谨慎起见，在发帖之前我又成功重现了此现象，不过没截图。
I hope someone can translate this passage.
Best I could do:
My music player uses foobar2000, not English the official version, but the foobar2000 Chinese Forum ashin the finished version.
Since a rise to 7, I opened up I never checked automatically sandbox feature, open foobar2000 when a sandbox module starts, choose ten seconds after the next normal start foobar2000 installation path so to exclusion of the sandbox module path.
Small a the upper right corner of the main interface set the bottom of the “Troubleshooting” point, the settings revert to default settings reboot, open foobar2000 no longer pop-up sandbox prompt box, I was puzzled to open the sandbox settings interface, found to exclude The path was empty.
I hold psychological try the uninstaller control panel, select repair, repair interface probably read all settings revert to default "such a meaning, the repair is completed manually restart and then open foobar2000 pop-up sandbox tips box.
Said so much about the meaning that if there is a program to run a pop-up prompt box sandbox select the next normal start, but with the main interface settings “Troubleshooting” restore default settings, the next run the program would not be small a pop-up sandbox prompt, although the sandbox set up inside the exclusion path has not. If you want to make it pop-up will have to repair the small a in the uninstall program.
A precaution, before posting I successfully reproduce this phenomenon, but no screenshots.
