#24 After opening drive, next file behaves weird

[Kimmo Varis]

If I open normal file after having disk data open and don't specifically select "Close" for the disk, Frhed goes into some mixed file/disk mode. And doesn't even seem to close the disk data.

To reproduce:
1) Open drive
2) Open normal file from MRU list

Expected: File is in edit mode, behaves normally

Actual: File is in read-only mode, disk controls are enabled

And if you select "Next sector" -button from toolbar it goes back to drive!
