vnetsup.vxd slows computer down

Kind folks,
I posted here about a year ago, and again have need (I think) to use
Microsoft Networking.
When I enable vnetsup.vxd, every program takes about 15 seconds before
it starts to load -- double-click, then wait. I haven't seen any CPU
loading or anything during that time, just the delay. Networking itself
works fine, once, say, Netscape is loaded.
Any ideas? I either need to find another way to share my printer and
files with my wife's Windows XP box, or I need to do something different
with vnetsup.vxd. I've got version 4.90.0.3000.

Any help or advice would be greatly, greatly appreciated.
