Hi @seanbudd @LeonarddeR
I reproduced the same issue on NVDA's log viewer, so I changed the title.
Can you look into it?
Thanks

I changed the description and title to be clearer, this is a bug in NVDA can you take a look? This will affect all applications that use WX rich text boxes.

Thanks

Hi,
Has NV Access noticed this problem?

[LeonarddeR]

I looked into this briefly, but all seems right for Wordpad which should be using the same control. Therefore I'm afraid that we can't do much about this.

[cary-rowen]

Thanks for noticing this, Does WordPad also use WXPython controls?
The samples I used to reproduce this issue all use the WXPython control. Is it related to WXPython?

Hi! Does it occurs with the latest alpha version of bookworm, downloadable from the artifacts of the latest commit?

I just enforced UIA in these controls and there, it seems to work. Therefore it could be that NVDA is missing something essential here.

[LeonarddeR]

I think the underlying issue might be that NVDA is using ITextDocument under the hood while UIA does not. When I disable the use of ITextDocumentTextInfo in NVDA, the caret follows nicely.

Hi, @LeonarddeR

Thanks again for the more detailed information!
I'm new to NVDA development, this seems to be a UIA bug, in your opinion, can it be fixed in NVDA using another method?

Thanks

Hi @zstanecic

As far as this issue is concerned, bookworm may not be able to do anything.

Thanks

Hi, @michaelDCurran @LeonarddeR
What is the possible progress for this issue?

[cary-rowen]

Hi, @seanbudd
Based on @LeonarddeR's message, do you have any ideas for addressing this in NVDA?
