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...

I can think of one place in the application where, if I remember correctly, this issue happened more than once. I will review the code in that section and make sure there are no obvious issues. I will also check the event/error logs next time it happens and see if I can find a pattern.

After your BUMP, we discussed the two situations they could recall some specifics on. >From their view, the compiled 9.1 (64) app had stopped and it was a display/memory issue, kill it and restart. I don't know that I agree with that assessment, but there was no database corruption, and no orphaned data left from the operations that they killed. I don't think it was an infinite loop running corrupted code or a process on a corrupted temp table, but it kind of sounds like it. We have approx 100 users, including 35 Citrix/RDP users all working in the same database. The problems they saw were never a Citrix/RDP session. The users that experienced the ghosting issue run Window 7 Pro with four different compiled RBase apps concurrently, Outlook 2007, and many other programs, and two different browsers, all at the same time. They have occassional random weirdness on their systems but it happens to the non-RBase apps also. I put them on the alert to NOT kill next time and to let me take a look, if it ever happens again.

The first one happens at random on different computers. While the application is just displaying a menu and doing nothing otherwise, the form/screen will begin to flicker rapidly and the only way to exit the situation is to kill the application through the Windows Task Manger; the users have called this condition "ghosting." This happens even when running the application directly on the server via RDP, so loss of connection is not the cause. The second happens when scrolling reports on the screen (70 pages). Once the report is generated and I start scrolling down the application, it will abruptly crash. There is nothing unusual in the report and it does not happen all the time; I can re-run the same report and it will display and scroll correctly. I am running a compiled version of 9.1 (9.1.5.20519). Has anyone run into similar issues? Javier, Javier Valencia, PE O: 913-829-0888 H: 913-397-9605 C: 913-915-3137
