RichEdit Vertical Scroll Problem

[mike1950r]

Hi,

I have a problem with vertical scroll.

Run the attached script and click on horizintal slider, vertical slider etc.

the text jumps up and down.

Is there a way to get rid of this?

Thanks for help.

Cheers mike.

I'm not sure what text is jumping. It looks fine to me.

Hi Andreik,

just scroll to last line and click on horizontal slider and then on vertical slider and so on.

the last line goes up and down.

cheers mike

I can't reproduce the described behavior on Win 11.

[mike1950r]

So it seems to be a windows problem?

I'm on windows7.

Thanks for testing.

Cheers mike

I can also reproduce this on windows 7, the last line gets hidden when you click the horizontal slider button, but only after having pushed one of the vertical scroll buttons, it doesn't do it right away for me, if I haven't pushed one of those first.

I don't know, maybe. I simply don't see this behavior on my machine with Win 11. Hope anyone else can confirm.

thanks for your posts.

I have recorded a gif-video to be opened with your browser.

It's for showing how it is visible on my system.

Cheers mike

Okay, sorry, I misunderstood. But I can reproduce that too. As for a fix, I unfortunately can't offer any suggestions.

BTW

This problem does not occur using _GUICtrlEdit_Create instead of _GUICtrlRichEdit_Create.

Cheers mike

PS Perhaps a workaround ?
