Kenny, The 3 workstation that experience the problem are all running Windows 7-64 and they all have the same graphics card. They will swap one the workstation with the problem with another one that doesn't and see what happens. In my case, it happens the majority of the time when the user is not even using the computer and the application is just displaying one of the menus which starts to rapidly flicker. I have experienced this twice while remotely connected via Cisco VNC and RDT.

This time it's a different part number and the number from Friday works fine. It appears that it only happens on Windows 7 32 and 64. I have tried on many computers and XP has never failed. I tried compatibility mode on Windows 7 with no improvement. The DB is on the network. We just tried a Citrix session on Server 2008 R2 and it worked fine. Only Windows 7 fails and it is rare, but now I can replicate it. Tried running it in compatibility mode with same results. Is your issue in Windows 7 only? I am going to take this issue off list and run a couple of more tests and then bundle up a copy and send it to RBTI to see if it does it for them. Below is a description of the problem and my observations. Kenny -------------------------- The display looks like it is trying to paint the form, and fails and tries again. Each of the three different forms pop up for a while, partially drawn and then is replaced with another. This looping behavior has now been going on for 30 minutes, where the normal program display is almost instant. Sometimes I see the outline of all three, but none in focus. Watching the task manager while this "ghosting" is happening, on the application tab I occasionally see additional tasks appear for a second with the form caption as its title and then they disappear. It looks like it is launching additional tasks? The CPU usage has now settled to 0 to 8% CPU usage and 30% of Physical memory and continuing to try to display the one record found on the scrolling region. Sometimes it almost completes the form, but then retries from scratch and does not get as far. Sometimes never showing the scrolling region at all. All other operation on the computer are fine during this problem.

This weekend I could not get it to behave the same way. Still working on it though. I'll let you know what I find. Going to use my computer for a number of hours like last week and then try again.

As I indicated, it happens primarily on 3 computers and I thought it could be related to the graphics driver or a bad network connection, but it has also happened to me when accessing the server remotely via VPN and Remote desktop. I thought that that maybe the connection with the database was lost temporarily and became unstable but the majority of events happen when the application is parked on a menu with no activity happening.
