WordPerfect® 5.1 for DOS

Problem

Symptoms: The customer is on a Microsoft LAN Manager network. When he lists the files on a network drive, presses F7 to return to the editing screen, and presses F5 twice to return to the previous directory, WordPerfect instead does a List Files of the default directory. Solutions: WP is looking for the return value of the drive descriptor on an Int 21h, 1Ch call. F8h is the value that indicates a fixed drive, as documented by DOS 4.0 Technical Reference Manual. Microsoft LAN Manager returns a drive type of 0 which is an unknown media type. WP assumes that it is a diskette drive, and since F5, F5 only works on fixed disks, it does not work on Microsoft's network drives. WPINFO uses the same call to find out the drive types and will display Microsoft LAN Manager network drives as diskette drives in WPINFO. Microsoft is aware of the problem and may be taking steps to fix the problem.
