SBIE2102 message in FF 33.0.2 (Sbie v4.14)

[Mr.X]

Windows 8.1 EN x86 updated.
Sandboxie 4.14 licensed.
FireFox 33.0.2

Never had this problem before it showed up after upgrading to Sbie 4.14 and Firefox 33.0.2. The message just pops up every time after clicking the "Upload" button on the webpage before the file in red rectangle is selected to upload. As this issue is new guess it's a bug or incompatibility with this FF version:

I think this isn't a bug or an incompatibility. This is related to explorer's iconcache_48.db file size. When you try to upload a file, an explorer window opens. In that explorer window are icons. These icons are cached in that said file. Write operations to that file need the file to be copied into the sandbox. The file size is larger than the file size migration limit.

Possible solutions:

1) Increase the file size migration limit or
2) hide the message, as it doesn't cause issues or

(not recommend because unnecessary)

3) you could allow explorer.exe direct access to those files

Btw, this is not related to the latest Sbie or FF version imho. I have observed this on Win 8.1 many times before when an explorer window is launched from a sandboxed application.

Thank you. After studying the File Migration setting at Sandboxie Control I've chosen your number 2 solution.
