Hi,

A user of my app containing th Scintilla editor component (DLL v3.7.6) reports 
the following error 
<https://forum.quickaccesspopup.com/showthread.php?tid=3007>:

The cursor while in Editor almost always will be offset from its true 
location. It makes it difficult to edit text since you don't know where you 
are within the text. The attached image 
<https://forum.quickaccesspopup.com/attachment.php?aid=493> shows the 
cursor to the left of the period while the true location is at the end of 
the line. So if I were to press the delete key, it wouldn't delete the 
period but instead move the next line up to the end of the current 
line. The cursor can be 1 or 2 positions offset and it might have been to 3 
before. This makes it more difficult to edit since it's not consistent and 
you can't account for it.

Only one user reported the error. He is using Windows 11. I can't reproduce 
the issue on my dev and test systems (Win10 and 11) with various 
resolutions and scalings.

Have you ever seen this issue with other implementations of Scintilla? What 
should I investigate to locate the source of this issue?

Thanks you for the great help found from this group's users!

Jean
