Summary: 40tude Dialog - richedit control refresh lag
           Product: Wine
           Version: 0.9.26.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-richedit
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This is a somewhat irritating bug in richedit controls (probably - I'm just
guessing) that has been present in older builds of Wine too when running 40tude
Dialog. Of course, this bug does not happen in Windows.

Steps to reproduce:

1. Create a new post
2. Enter the following in the field:

Line 1
Line 2
      <- an empty line
Line 3
      <- an empty line

Then, position the cursor on the beginning of line 3. Press backspace.
Explanation: as expected, the first empty line is deleted and line 3 is pulled
where the first empty line was. We expect this:

Line 1
Line 2
Line 3
      <- an empty line

...but we get this:

Line 1
Line 2
Line 3
Line 3

The reason is that the second empty line is pulled in place where line 3 was, as
we expect, but the place where line 3 was is not properly refreshed and we get a
ghost image of line 3 on the second empty line. It we minimize/unminimize the
window,  drag it offscreen and then back - scrolling does the trick too - we get
what we expected, but this is a rather annoying bug. I'm guessing it's a bug in
richedit controls.

Tested on Wine 0.9.26 and Ubuntu 6.10 in GNOME, 40tude Dialog 2.0.15.1 b38.
