You are probably running in 24-bit mode. In that mode, your system cannot 
access more than 8 Meg of memory. Any extra is charged to the system, 
although in fact it's not used. So your system is using 1 Meg, ignoring 
another 2, leaving 7 for your apps.

Open the "Memory" control panel and turn on 32-bit addressing. (If there's 
no control for this, then the LC can't do it - but I think it can.) 
Restart your machine. You should now find that the "missing" two megabytes 
are available for use.

There's a price to pay for running in 32-bit mode: lots of old apps aren't 
"32-bit clean" and will bomb in 32-bit mode. (So make backups, then 
experiment cautiously.) That's why it's an option whose default is "off". 
Contact the companies that made the incompatible apps to ask about 
upgrades.

Hope this helps.
