Windows indexing has stopped working for me after upgrading from 1.3 to 1.4.
Version 1.4 (v188.8.131.527 to be exact, running on Win7 x64, all updates applied) does not allow me to put a checkbox next to the mapped drive in the "Control-Panel->Indexing Options->Modify" dialog. When I single-click on the checkbox next to the encrypted drive, nothing happens. If I double-click it "opens up" the drive (same as if clicking the small arrow). All subfolders are equally "un-checkable".
Uninstalling and reinstalling does not change things. I also tried using "Show all locations" (i.e., admin rights), all to no avail.
I noticed this problem first on my laptop. As my desktop machine was still running 1.3 I tried the same there and was able to select and unselect all encrypted drives. After updating my desktop to 1.4 (i.e., same version as referenced above), the same problem occurs.
Let me know if you need additional information (I tried running boxcryptor with the "/debug" flag but the logfile doesn't really seem to contain any particularly relevant information/errors/warnings)...
