[comp.lang.postscript] MS Windows 3.0 and PC/TCP

From:  wolfy.csd.unsw.oz.au

My Platform:
	NEC 386/20  2Mb RAM
	Windows 3.0
	Racal Interlan 6510 Ethernet Adaptor
	FTP Software PC/TCP
		using Resident Module Version 2.03 pl 3
		Packet Driver Type 35

My Problem:

The TCP resident module occupies approximately 83K of valuable memory that I require most of the time.  I can load the module before I start Windows.  This works and I can swap windows, but I do not have enough memory to do anything useful.  I would therefore like to load and unload the module as it is required.  I have written a batch file to load the module, open a command shell and then on exit from the shell remove the module.
This process works correctly and all communications occur as they should.  The problem occurs when I attempt to swap to another window with the module loaded.  The system hangs.  I have tried all possible combinations of PIF settings in an attempt to stop this occuring.  These efforts have proved fruitless so far.
Has anyone got any ideas?? If not I would love an explanation just for my enlightenment...
