Hello Syntax Edit team,

I just want to make a proposal for the following effect (what - I think - is a bug).

Suppose I have a text file with 2 lines:

1234567890

ABC

So 10 character in the 1st line and 3 characters in the 2nd line.
Then I press <End> to go to end of 1st line. Then I press <Down> to go to end of 2nd line.
I brings me behind the 3rd (so the last) character of 2nd line. So far, so good.
But when I now press <Shift>+<End>, it draws, as if 7 (non-existing) space characters

were selected. But they are not (because I cannot copy them to clipboard, etc.).

Note: Virtual space is NOT enabled for my syntax edit control.

So I would suggest the following fix in file "XTPSyntaxEditPaintManager.cpp" in

function "CXTPSyntaxEditPaintManager::DrawLineTextEx" ca. in line 1023:

Replace:

...

    if (!pDC->IsPrinting())
    {
         // draw selection for virtual space, after line text end)

...

with

...

if (!pDC->IsPrinting() && pEditCtrl->IsEnabledVirtualSpace ())

{
// draw selection for virtual space, after line text end)

...

Because as the comment already states:
The following drawing code should only be for virtual space and if I have NOT

it disabled, it draws - in my opinion - wrong and confusing things.

So I simply so not execute this special drawing code when I don't have virtual space.

Best regards
