The 'fonts are very likely loading into RAM. You should have at least 1gig available, more is better.

There is also a known problem with certain softsynths, like the Forte, where revisiting the synth's Control Panel causes it to reload everything in it every time, not clearing the ones that were already in the RAM from the first time. Needless to say, that can chew up the resources available pretty quickly.

As far as other available soundfont players that are either VST or DXi, there are lots of offerings of various price from free to whatever price around the web these days, here's what a Bing search just returned:

By far I have found that outside of the old Creative Live! series cards, which loaded soundfonts via their own processor, software soundfont playing can be a catch-as-catch-can situation, with some working for certain people's setups, the same ones not working as well for others, likely due to differentiations in systems, setup, resources, etc.

Matter of fact I've moved almost entirely to hardware MIDI synths again here and have avoided a lot of those frustrating, "it worked fine yesterday..." moments.
