List,
All of a sudden several of my users are having many access violations daily while others, doing the exact same job (same forms and code) never have them. One thing the problem users have in common is they tweak the Windows desktop to different themes, font size, background color, etc. Could this contribute to the problem? I'm working on ways to deal with happy clickers, but they swear they don't do that. Thinking about a network cable tester $$$$. I have located one workstation location that is bad, because if I move the computer to another location, it performs much better. Anybody have experience with modern cable testers, I have one, but it's from the early 80's.

In my case, I isolated the problem to forms with DBGrids where I make use of the on click EEP. I discovered that some users would click multiple times (instead of once) causing various errors or erroneous results (including occasional access violations). To resolve the problem, I made use of the form timer to restrict the clicks to one. If your problem is similar to the problem I had, let me know and I will send you a copy of the code that I use. I am not in my office at the moment but I should be back around 2:00 PM and I will send it to you if you want to give it a try.

The one employee has no problems with the BOL form, while another employee constantly gets the Access Violations with the same form.

So if the server or the network is returning junk to the instance of R:Base running on the workstation, that could be responsible. And I have seen at least one instance where the exact same code running against the exact same database files worked on a PC and generated Access Violations (seemingly at random) on a networked copy of the database. -- Larry
