[GaryFrost 17]

if gridlines are added to the extended style, works fine unless using the down/up arrows at the top and bottom of the scrollbar

expandcollapse popup

I don't see such weird refresh under XP/Sp2 with or without the XP Theme. :">

Which OS version are you running with?

[GaryFrost 17]

XP Pro SP2, Windows Classic

[jpm 76]

XP Pro SP2, Windows Classic

<{POST_SNAPBACK}>

I run the same and I cannot see the problem :">

I made that script into a exe and tried it on a second system, same OS, still same problem.

[SlimShady 1]

Maybe something with the resolution?

Can someone compile the script and attach it?

you probably need to ZIP the file.

I'm going to test here then.

Yep, refresh bug.

Windows XP SP1

resolution: 1024x768

When using the mouse wheel to scroll, you see no bug.

As Gafrost said use the scrollbar buttons.

Both the buttons cause the refresh bug.

Something related with speed/video card ??? :">

[GaryFrost 17]

Here's info about 1st system, second system is even newer.

[jpm 76]

It is a paint problem on the listview control. If I drag another window over, the lines get fixed.

Why I don't need to do that?

[GaryFrost 17]

I tried the work around and that does work.

It's a shame that microsoft has know about the bug with the control for so long and hasn't fixed it yet.

[jpm 76]

Works fine when I drag the scroll button, but when I click the up and down arrows, I get extraneous lines (WinXP Classic Theme).

<{POST_SNAPBACK}>

Whatever I dclick the updown I cannot reproduce it on my system.

I will recommend the Larry Post suggestion use as less as possible the grid. At least don't expect a very good repainting

[jpm 76]

I just see the workaround it appear that I was using it !!!

@jpm: do you plan now to implement the "SystemParametersInfo" (thanks Larry for info) to get it works right?

(BTW: I also switched it off so I couldn't reproduce it at frist )

It is not our responsibility to fix Microsoft's bugs. We should be trying to provide generic GUI building capabilities. We can not override user-specified features at the OS level. That is bad design. There are 3 solutions to this problem:

• Live with it.
• Turn off the feature at the OS level on your machine.
• The script author can programmatically make the SystemParametersInfo call themselves (Although this is still bad UI design since it does not take the user's settings into consideration).

AutoIt should not be responsible for fixing this bug.
