23 Nov 05 Editable display table does not fully support SVG graphics. Chromosome can be editted but other fields give empty image. This is due to missing support for w, wf, sf, vf. 24 Nov 05
22 Nov 05 Badly formed SVG code may be generated. This causes large numbers of errors like Error: Expected color but found 'undefined'. Error in parsing value for property 'fill'. Declaration dropped. for Source File: data:image/svg+xml, Line: 0 to be reported. However pfeiffer_local.html continues unaffected. 22 Nov 05
22 Nov 05 If default initial Lindenmayer grammar specified via pfeiffer_params.html did not supply defaults (eg because it was badly formated) pfeiffer_local.html stops after a few seconds, initial flakes disappears and exception Expansion has no properties in lsys.js is raised. 22 Nov 05
11 Aug 05 With Deerpark and Scalable Vector Graphics wrong picture may be displayed in the table after editing it. Correct picture may be displayed in main window. See bugzilla 304334. Appears to be fixed in Firefox 1.5. 23 Nov 05
29 May 05 Firefox 0.10.1 Occasionally generates warning caution box xmlhttp.send() .... Langdon/log etc etc failed due to:
[Exception..."Component returned failure code: 0x8004005 (NS_ERROR_FAILURE) [nsiXMLHttpRequest...

   This indicates a problem logging data (cause unclear at present).
   Work around: Click "OK" and pfeiffer will continue.

13 Nov 04 An IBM PC running windows may not recognise the XBM graphics file type. This prevents microsoft internet explorer correctly displaying XBM images.
   It has been suggested that microsoft service pack 2 (SP2) breaks internet explorer on windowsXP 5.1. If this is true of your computer, please consider using the server version or options 2) or 3) below.
   Work around: 1) Reconfigure the PC. 2) Use server version (which generates GIF format) rather than local version which runs inside your browser. 3) Use another browser, eg Mozilla Firefox or Netscape 7.2
Local version can now also down load GIFs from server.
   The Table describing population option uses lots of CPU if the browser is not displaying evolved flakes correctly. Work around: 1) 2) or 3) above, Or iconise Table of Pfeiffer Data window when not in use.

2 Mar 07 With Ubuntu KDE 3.5.5 Konqueror 3.5.5 counters update and evolution continues underneath. But no images are displayed.
   Work around: use another browser, eg Mozilla Firefox.
13 Nov 04 Suse Konqueror Linux PC browser may fail with a status line saying "Requesting XMLHttpRequest"
   Work around: Use another browser:-(
9 Mar 04 With Mac Safari/124 the initial fixed snow.gif images flutter about the screen and evolution continues underneath. But the evolved images are never displayed.
   Work around: use another browser, eg Mozilla Firefox.
10 Mar 04 Mac internet explorer 5 fails in fetchURL a few seconds after loading pfeiffer_local.html. The status line shows "Chromosome 0 -60 c0 u".
   Work arounds: Either (1) Use another browser, eg Mozilla Firefox.
   Or (2) Run in local mode by clearing "Internet seed supplier", "Internet seed storage. Ie location to store your nice flakes", "Internet seed logging. Ie location logging both good and bad flakes" fields in pfeiffer_params.html and then restart.
8 Mar 04 Internet explorer 6.00 can fail to start second or subsequent animation window after successfully starting it. I.e. second time start button on pfeiffer_params.html is pressed new window is created but animation does not start and no snow flakes are displayed.
   Work around: reload pfeiffer.
15 Mar 04 Mozilla restricts the length of input which can be entered into fields on editable Table. This mainly effects the "Drawing commands" field. When editing the last field in the table, user should be wary that their input may be truncated by their browser. This can considerably truncate the flake generated on the screen. (Note maxLength is -1 but Mozilla 1.5 imposes a limit http://bugzilla.mozilla.org/
   Work around: The effect you want might be obtianed by editing another field, eg "Chromosome".
8 Mar 04 Clone operation on flying menus does not work. 8 Mar 04
8 Mar 04 Documentation, pfeiffer/overview.html, refers only to old (June 2003) system. 8 Mar 04
7 Mar 04 Netscape navigator 6.00 does not work under microsoft windows on a PC.
   Work around? Possibly upgrading to later version of Netscape 6. Need at least 6.1 but note various security issues have been suggested for Netscape versions 6.1-6.2.2.
   Netscape 7.2 appears to work ok.
