Hello everyone, I’m working with beta (actually 12.9.0.43) and using editor a lot. In few words: typing in the editor some new query or pl/sql or simply editing a query (for example to add a comment) I got an Access violation in module ‘Toad.exe’. I grabbed few EurekaLog, can be useful ? This issue is annoying because when typing whitout looking the screen often the next key close the error popup and the result is that some character are not written in the editor. Sorry for my poor english, hope that could be solved. ---

If you locate Toad.el in your User Files folder and post that it will contain a log of all recent exceptions. ---

You have many AVs in that log and most are failing at a single point in the code. I’ve seen AVs come from this area before, but looking at it again today and I think I have made is safe finally. Please grab the next beta (early next week) and let me know if you continue to have problems or if Toad seems to have stabilized. Thanks, Michael ---

I’ve tested the new 12.9.0.45 but seems to have the same problem. Attached the new Toad.el Hope this will help to solve the problem. [Toad.45.el.txt](https://global.discourse-cdn.com/quest/original/2X/d/dcd2a7000441bd6bcd8e6e55e4406e3a75c14730.txt) (611 KB) ---

Thanks for the update. On the bright side, the AV has moved. 🙂 The failing routine is largely the same as before, but one is in Toad’s source and this latest is in third party source. I’ve made a change there as well for next beta. Please let me know what comes of it. Thanks, Michael ---

Thanks for the update. A pointer to a string is no longer good it looks like. What exactly are you doing leading up to the error (typing, pasting, etc.)? Is there a common set of steps to them or not really?

I’ve taken one more stab at it. Let me know what comes of it. If you’re still having problems I’ll bring in some others more familiar with the code to have a look with me. I’ll be away for a bit, but will revisit when I return. Thanks, Michael ---

12.9.0.49 still has the problem, it appears often when editing sql queries and using backspace to delete characters. Seems to be related to the red icon that appears when there is an error in the query - if there is a way to disable the real time check of the query, I could try removing that to see if the error disappear. btw this is the new toad.el related with the new beta. regards!

I just got back to work after some time away. I’m catching up and will revisit this sometime this week. It looks like the fix is not far enough upstream. Thanks, Michael ---
