File (*.exe) stays locked

[artelogic]

I am using Delphi (development environment) on Win7.x64 host in WinXP.x86 guest. When I compile a programm to a shared folder and run that program within Delphi, the newly created EXE stays locked after exiting it. So I can't compile it again nor can I delete it from within the guest (Cannot delete abc.exe: It is being used by another person or program) nor from the host (file in use by VirtualBox.exe).
Is there a hack, am I doing anything wrong or is it just a bug?

In the log I found those:

Code: Select all

I'd say its a bug, but then again shared folders are be far not what its suppose to be, a reguliar network share will work as it should.
