We were able to duplicate the problem and verify that it has been fixed in Macintosh PC Exchange 2.0.1 and later. Below are the steps used to test PC Exchange 1.0.5 and 2.0.1.
System configuration: Quadra 610 DOS Compatible, 8MB RAM with a 160 MB Hard drive, and System 7.1.
1) Formatted 2 floppies on a Dell 486DX/50, hereafter called Disk 1 and
Disk 2.
2) Copied various files to Disk 1.
3) Copied Disk 1 to Disk 2.
4) Loaded Macintosh PC Exchange 1.0.5 on Quadra 610, and restarted
computer.
5) Insert Disk 1 into Quadra 610, and launched SimpleText.
6) Select "Open" from "File" menu.
7) When STDFile Open Dialog box comes up, click "Desktop" button, then
double-click Disk 1.
8) Open text file on Disk 1 from SimpleText.
9) Close text file without modifying and quit SimpleText.
10) Open Disk 1 from the Finder, viewed by name and found all modified
dates changed to current date and time.
We then tested Disk 2 with PC Exchange 2.0DC.
1) Loaded Macintosh PC Exchange 2.0DC on Quadra 610, and restarted
computer.
2) Insert Disk 2 into Quadra 610, and launched SimpleText.
3) Select "Open" from "File" menu.
4) When STDFile Open Dialog box comes up, click "Desktop" button, then
double-click Disk 2.
5) Open text file on Disk 2 from SimpleText.
6) Close text file without modifying and quit SimpleText
7) Open Disk 2 from the Finder, viewed by name and found all modified
dates have not changed.
The results were the same for Macintosh PC Exchange 2.0.1 as they were for
Macintosh PC Exchange 2.0DC, it looks like the problem has been fixed.
