Problems with timely writes from win98

[Brian Bagnall]

It takes up to 45 minutes to write a file to disk from win98.
The file appears to be written from the win98 side but 
is not actually updating on the disk until 45 minutes later.

I am running 2.0.2 and I have just looked at the oplocks options
and I am implementing it now.  But this seems like a larger problem 
due to the incredibly long delay.

Can someone direct me to some documentation about this?
