Works now for me too - that was a fast fix, tzuk. Btw, this issue also affected Media Player Classic.

Yep, working perfectly here as well!
If you dont mind me asking, I was just curious, what was causing the issue in the first place?

[tzuk]

I changed the way Sandboxie allocates its memory in the sandboxed process so it grabs memory at the top of the address space rather than all over the place.

The intention is to make the address space of a sandboxed program look as much as possible like the address space outside the sandbox.

Also by moving that stuff out of the way, sandboxed programs that have memory corruption issues (which somehow don't severely affect the program itself) are less likely to interfere with Sandboxie data.

Anyway this revealed a problem in the "Wow64" parts of Sandboxie which were messing up those "high" address ranges.

Again I'm sorry that I did not notice this prior to releasing version 3.53.07. I did test some stuff on 64-bit Windows but for some reason (I did not bother to check why), the 32-bit Internet Explorer process does not have this problem, so I did not notice the problem.
