Crystal Report + VB6 through VPN

Hi All.. I have an application which is using VB6, Crystal Report 8.5, and Ms.Access 97....

I put VB6 & Crystal report file on ComputerA and Ms.Access on ComputerB... ComputerA and ComputerB is linked through VPN (through internet)...
My way of printing report is to calculate all of my required data for report and saved it into table in Ms.Access97.. after that VB6 will connect through ODBC to get the data from Ms.Access97 (which is on ComputerB)....

My problem is I can print the report fast on the first printing, but on the next printing, it may take longer... but when i closed the whole application, then i open again, it works OK just for the 1st time and the rest will be lag again... May somebody know what is the problem? Is that any possibility that Crystal Report 8.5 is the problem?

I want to execute report as your way (through VPN_Internet), can you help me to fix setting of Crystal Report.

Thank you ;)
