  20 BUG NUMBER:             1
  21 SHORT DESCRIPTION:      Popup menu bug
  22 DETAILS:
  23 If a popup wxMenu is destroyed after its parent window has been
  24 destroyed, we get the message "Object XXX does not have windowed
  25 ancestor".
  26 Possible fix: call menu->DestroyMenu() before deleting the window,
  27 if the window knows about the menu that was last popped up (hard
  28 to know this with confidence).
  29 WORKAROUND:
  30 Delete the menu before deleting the window on which it
  31 was popped up.

  40 SHORT DESCRIPTION:      Misc. Motif bugs
  41 DETAILS:
  42 - In wxGrid, cell highlight is not drawn/erased properly.
  43
  44 - Setting the size of a hidden window may show that window.
  45
  46 - wxRadioBox sometimes doesn't show (e.g. in controls sample).
  47
  48 - Can't set the colours for the buttons in the file selector, for
  49   some reason.
  50
  51 - On SGI IRIX 6.4, XtDestroyWidget in ~wxWindow causes a crash in
  52   some cicumstances. This is being looked into. Meanwhile, a
  53   possible workaround is to remove the final XtDestroyWidget line in ~wxWindow
  54   (window.cpp). This will mean that child windows will only get
  55   destroyed when frames and dialogs are destroyed, so dynamic subwindow
  56   deletion may not work properly.
  57
  58 - There are reports that scrolling can cause crashes under Lesstif.
  59   This is probably a Lesstif bug.

  69 SHORT DESCRIPTION:      Dialog Editor issues
  70 DETAILS:
  71 Dialog Editor could be more user-friendly. Controls are hard to
  72 size and position accurately. No way of changing tab order
  73 except by editing .wxr file.

  84 DETAILS: I haven't tested it throughly, though it happens when appending a submenu
  85 WORKAROUND: Add dummy id number even for menuitems which don't require them (submenus for example)

  91 BUG NUMBER:             5
  92 SHORT DESCRIPTION: no vertical space inside wxHTML
  93 DETAILS: We are working on making a demonstration of projects we do here
  94 using Python & wxWindows & HTML (wxPython/wxHTML thus). We 'd like to
  95 have the opportunity to specify vertical space, eg <br><br>, or <p><p>
  96 in HTML. These constructs currently do not work. I looked in the source
  97 code (nice job btw), but am not sure where to hack the solution. I
  98 am willing to discuss this in more detail.

 136 SHORT+DESCRIPTION: misnamed setup.wXX files prevents install
 137 Submit: Submit
 138 WORKAROUND: The problem seems to be that the default download name for the setup.wXX files is not 'setup.wXX' but instead 'setup.wXX..wXX'  Every new user who installs could change these names... but why not simply change them on the server?  (I was using IE 5 under Windows 98)

 205 DETAILS: Around line 1234 or the common/docview.cpp file following code exists...
 206
 207 if (!theTemplate)
 208     theTemplate=templates[FilterIndex] ;
 209
 210 The problem is tat FilterIndex is one based and the templates array is zero based. The correct
 211 thing might be to use FilterIndex-1 as the index. Else the following scenario will
 212 cause a crash.
 213
 214 1. Use the docvsmdi example
 215 2. Bring up the file open dlg.
 216 3. Select Files of Type "Text"
 217 4. c:\autoexec.bat for file name
 218 5. Press okay and you should see
 219    the crash.
 220
 221 I understand that it is very
 222 hard to figure out the template
 223 when the user does not select
 224 one of the known extensions but
 225 this simple fix might atleast
 226 avoid the crash....
 227
 228 I started playing with wxMSW
 229 just this morning and have not
 230 yet figured out exactly how to
 231 submit a fix. I atleast wanted
 232 to report it. Besides what I do
 233 for the MSW might not be correct
 234 for the other platforms :-)
 235
 236 Note from JACS: fixed (I hope) by making m_filterIndex
 237 zero-based in MSW wxFileDialog implementation
 238 (it's zero-based in wxGTK/the generic dialog).

 251 DETAILS: wxGTK cannot seem to find the default font
 252 on (some?) Debian 2.x systems.  This results
 253 in infinite recursion in wxLoadQueryNearestFont.
 254
 255 It only happens on one of my two Debian machines,
 256 but I haven't investigated thoroughly enough to give
 257 any more detail.
 258
 259 I have made a temporary workaround by trapping
 260 recursion in wxLoadQueryNearestFont with a static
 261 bool flag.
 262
 263 I will investigate the problem further if this bug has
 264 not already been reported by someone else.
