Flicker

yes, it was set to ADO.NET

FYI: I closed SSMS and reopened it and the flicker came back. I had to enable and disable the spell check again. It seems like the setting isn't sticking?

The settings are stored in the config files and some in the registry. They are not sticking when Windows is undoing them after you logoff. To make these change permanent, please start SSMS in Run As Administrator mode, make the required changes in the settings and then restart SSMS normally or just turn off UAC.

I don't think you undserstand. It looks like its disabled but stil flickering. I have to enable and then disable to get it to stop. I do not logoff. I just restart ssms and it come back.

We are likely talking about different things. I didn't mean spell checker. Spell checker is dormant until you manually activate it. I meant SQL syntax checker. To disable that feature, wait for the syntax bar to appear on the right of the editor screen, the right-click it and select Auto check -> Off menu. This should help.

The flickering is most likely a result of your remote system slow screen repainting. The syntax checker is drawing wavy red lines and other things on top of the SSMS normal screen and this leads to additional screen repainting after each scroll, text change, etc…, which is normally not an issue and not visible when working with a local editor.

right, but why does it stop if I enable and then disable spell checked and why doesn't it happen in 4.8?

The flickering sounds like the same experience as in this post:

thank you birgerii. Does it come back for you after you restart SSMS?

I've tried to disable as much as possible and restarted as well, but it still flickers. Even when I just step through the code using the arrows.

Just in case, SQL Assistant is setup and running as a SSMS add-on? not attaching to SSMS from the system tray application?

I don't know how to run it as an add-on. And I run mostly SQL Query Analyzer, and it flickers a lot on every key release.

You stated in the initial post you are having an issue with SSMS, that's why we focused on SSMS

Is that a remote desktop connection, Citrix, remote terminal session, or something similar? If yes, is that conenction slow?

In my initial post (http://www.softtreetech.com/support/phpBB2/viewtopic.php?t=23096&start=0&postdays=0&postorder=asc&highlight=), I told you I was using Query Analyzer, it is "neverden" that has the experience with SSMS.

I notice the flickering even if I run SQL2000 on my laptop:

Is there any text highlighted when you see the heavy flickering? Any SQL Assistant windows/panes/bookmarks open? If yes, on which side of the SQL Query Analyzer window?

Does the amount of flickering depend on the size of the script in the editor? Does it depend on the syntax checker enabled/disabled state?

No text is highlighted
No SQL Assistant windows/panes/bookmarks open
I can't say that I notice any difference between 50 rows and 1000 rows

No significant difference while stepping through the code when syntax checker enabled/disabled. If enabled on three seconds, a quick flickering can be noticed after three seconds of none-movement.
