Internet Explorer fails to display correctly some aspects of pages generated by elog when the zoom functionality is used (Ctrl + and Ctrl -).  This is really a bug in the IE renderer rather than elog, but since IE can be persuaded to do better relatively easily it might be worth making some minor changes to make elog more robust when used with the buggy Microsoft browser.

The problem I encountered was initially with the multiple checkboxes for an Moptions attribute, but I noticed later it also affects the logbook tabs at the top of the screen.  If you start creating a submission to this forum in IE (7 or earlier, at least) you can see the problem; when zooming, the text labels and  the checkboxes do not scale together so start overlapping, and the same happens with the logbook tabs and the text links on them.  The problem is apparently to do with a proprietary IE concept called "layout" - see http://www.satzansatz.de/cssd/onhavinglayout.html for details - and IE struggles when some elements do not have the hasLayout property set to "true".

The fix is to coerce elements to have the hasLayout element set to "true" by giving them some benign CSS property.  The best I can find is to set "display: inline-block" for some of the key elements, and this can be done by modifying default.css rather than the elogd.c code.

Adding

span {
  display: inline-block;
}

to default.css (e.g. just after the default style definition for the "td" element) and adding

  display: inline-block;

to the style sets for the .sltab and .ltab classes (generic, not those specific to the "a" element) seems to prevent IE doing bad things with the display when zooming without messing up the display in Firefox.  I have not tested this comprehensively or in any other browsers, but I thought it might be worth passing on.

Cheers,

I just tried with IE8 (don't have IE7 installed any more), and it looked to me like this has been fixed there. So this will get less a problem in the future. If people are stuck to IE7, they can made your modification themselves in the CSS file, so I guess I won't change the distribution for the moment.

Having made one entry in the thread about message ID, I could neither edit the entry or add an additional reply
without getting "Proxy Error" messages.  I've had this trouble on this forum before, a long time ago.  Perhaps
it is connected with the html coding?

Hi Stefan,

I now cannot even reply to you in the message id thread; I keep getting:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request POST /elogs/Forum/.

Reason: Error reading from remote server

Apache/2.2.3 (Scientific Linux) Server at midas.psi.ch Port 443

It is, I think, something to do with the html coding (as I normally use plain, I don't come across this as an issue).

However, in the cause of the experiment, I will submit this entry, then go back and edit it, and if I don't get
Proxy Error, then that certainly will be something to do with the html coding.

And this is an extra edited line - if you see this, I got past the proxy error issue this time.  But did you get two
emails?

That is interesting.  I can make 1 (one) submission to a thread which uses html coding, then I get hit by proxy errors. 
But I can edit, play around or whatever if it is in plain coding.  Yet to see how many emails were generated...

Hi Stefan,

I only got one email in response to the second entry of this thread, no email was received after the edit of the entry.  The
next email received was due to the third entry of this thread.

Ok, let me try (sorry to all the users who subscribe to this forum for pestering you...):

1st reply to your entry.

1st reply edited.

I got two email notifications, the second one I attached as a screen shot. So I don't know what happened in your case. The problem 
with the proxy is sometimes related to slow internet connections. If the HTML code transported over the internet has some delay 
between packets, the proxy server sometimes drops the connection. I don't know how to fix that in my Apache. If you edit in HTML, 
your browser downloads the JavaScript code and icons for the edit window, which is a lot of data, so the dropping is much more 
likely.
