Sandboxie 1301 warning message when exiting browser

[jw72253]

Hello. I have Sandboxie version 3.70 (64 bit) on 64-bit Win7. I use it primarily for the browsers. I have 64-bit Internet Explorer 9, which I run inside a sandbox. Whenever I "exit" the browser program, Sandboxie gives me the same warning message (SBIE 1301)as it normally would give when starting a program outside the sandbox. I do have "iexplore.exe" set in Program Alerts. I don't recall it ever doing that in the past, when I was using it on a 32-bit Windows XP OS.

It should not be giving me a message like this when I close the browser, I don't believe? Is there something I can try to correct this? Thanks.
