I am having trouble using XMDPW5.CO by Phil Wheeler (and others) under XOS-C on the T200. With XMDPW5.CO in bank 3, I access it using F3 (CMD>xmdpw5) or directly using XM-LDR.BA (made from your MAKLDR.BA). All is well until I log off, and try to return to the T200 Main Menu by hitting F8. When doing so, the computer locks up tight. The RESET button is no help and a cold start is required. I have experimented enough to find that this crash does NOT occur if I have NOT downloaded or uploaded using XMODEM while on-line.
Note: If I had accessed XMDPW5 using the XM-LDR.BA file, both banks are crashed.
I have studied the XMDPW5.CO source code placed in the M100SIG, but I am not yet skilled enough in Assembly and the T200 to know how to fix this.
