Yes vmm32 grabs whatever it can, although I believe it can be setup 
herwise.

Yes, but how is it done??  I have a shortcut to 4dos.com on my desktop.  In 
the properties > memory there's a setting "Uses HMA" which can be checked or 
unchecked.  This is the only thing I can find which seems to tell win95 that 
the app uses this type of memory. I assumed this was what allowed it to 
access UMBs.  But it mustn't be, as I've checked the box but it makes no 
difference,
4dos still gives the startup error that UMB's aren't available.
I've used the [secondary] directive (as mentioned by Bill Drake) in 4dos.ini 
to get around this problem.  But as you say, I thought win95 could be setup 
to allow the use of UMB's to certain apps, etc.
Rgds, Vic
