The problem is now hiding from me again. 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.

Unfortunately in my case , there is no pattern. More than half : of the events happen while they are not doing any work, the application is : just sitting on the screen while they do other things and suddenly the : application starts flickering on the screen; all other concurrent : applications continue working properly, : This issue happens mostly on 3 computers and I thought it might a bad video : or network card but it also has happened to me a couple of times while : connected remotely via VPN and RDP. I will see if I can get diagnostic dump : next time I run into it. BTW, The system was upgraded last weekend from 9.1 : to 9.5 and The problem is still there; I will download the latest release : and update the system over the weekend and see what happens. : : Javier, : : Javier Valencia, PE : O: 913-829-0888 : H: 913-397-9605 : C: 913-915-3137 : -----Original Message----- : From: [email protected] [mailto:[email protected]] On Behalf Of Kenny Camp : Sent: Friday, February 08, 2013 6:06 PM : To: RBASE-L Mailing List : Subject: [RBASE-L] - RE: Strange errors : : Javier, : : We finally found a way to reproduce this rare problem. In my compiled : application, several forms deep I have been reliably able to : ghost/flash/crash/whatever in the same situation 99 % of the time. The : really weird part is, that it only crashes when using one specific part : number 'M24308/2-5F' which is very close to many other part numbers that : don't ever crash. : : We use this same routine hundreds of times a day with no slow down or : problems with other part numbers. When I use this one part number, : sometimes (given lots of time) it will resolve itself and then all other : menus items including this same one will work fine as long as I use a : different number, it's like nothing ever happened. : : But sometimes, it will freeze the entire Windows 7 Pro (64) system requiring : a reset. Sometimes it just flashes partial forms from the background, or : shows the form it is trying to load, back and forth until I kill it. : : When using the full version, I haven't been able to : crash/flash/ghost/whatever only the compiled app. I moved copies of : everything off the network and onto my laptop, and it broke first attempt. : : Now that I can test, I should be able to remove objects and experiment until : I find some reason. : : I will report what I find, and RBTI will quickly fix it. : : I plan to test with 9.5 compiler this weekend as they may have already fixed : whatever this is. : : To clarify, the only way I have been able to crash/flash/ghost/whatever is : the combination of 9.1 compiler starting an external menu form calling a : variable menu form, calling a one table form with a scrolling region based : on lookup of the part number 'M24308/22-5F'. Any other part works fine. : : Going code error/bug hunting... : : Kenny : : : -----Original Message----- : From: [email protected] [mailto:[email protected]] On Behalf Of Javier : Valencia : Sent: Friday, October 26, 2012 2:53 PM : To: RBASE-L Mailing List : Subject: [RBASE-L] - RE: Strange errors : : All their computers are running Windows XP-Pro.
