>>>Because i've had the same problems with a application working with data on a WAN I applied the following:

>>>Where ever it is possible, try to use some kind of replication of remote data to a local network drive. This can be done with data that doesn't change to often or devolop a good replication mechanism.
>>>
>>>Use as much advantage of Rushmore. The gain of performance by using rushmore is tremendous. I found factors of 1: 1.000.000 (on very large tables) and more.
>>>
>>>It is more efficient to download a lot of data and use it for many modules than to download data every time you enter another module.

>>>I hope my suggestions will help.

oh - i see...i have done all of that. in the program, there is an option
called SELECT QUERY. when this option is use, the program uses a VIEW to gather
the new set of records. this takes a long time. if i used SET FILTER, it
probably would be faster. what do you think?
