through the grids (Scroll bars, page UP/Down, arrow keys, you name it) We are getting anywhere from 2 - 15 second lag times in the screen refreshing when navigating through the grids. Any advice for performance enhancements will be greatly appreciated.

1.) Why not have the EXE installed on remote PCs? This would improve performance.
2.) What is your data engine? And is it client/server? Passing entire datasets over the wire is the death of a system. Client/server limits the volume of data transmitted over the wire (based on your fetch rate and stuff). You may want to read some articles on client/server. Inquiry.com has some great reference material for example.
3.) Also, can any data files be stored as free tables on the remote PC. I have done this in the past to improve performance. Tables for validation of data for example.
4.) The slowness of the grid may be a function of the design of your form. Are U using pageframes. If so, U may want to read the threads and other reference material on this forum. There are some very good tips on how to really use pageframes. I am still living with a poorly designed pageframe system and life is difficult.
5.) Are U using optimized SQL stuff to populate the grid. Do U have all of you indicies setup?
Well, just some thoughts-hope this was helpful.
