First, a qualification: Since I got a flat-panel display at work, I no longer have my PC connected directly to the display; I view the PC’s video output via Remote Desktop Connection on my Mac. I’ve learned over time that RDC does not provide a direct, unaltered feed of the PC’s video. For understandable reasons (faster screen refresh), but by perhaps unjustifiable methods, RDC re-renders parts of the video display. The result is that you do not see a pixel-perfect (or even simply downsampled) representation of the actual PC video; it appears to be redrawn completely for network transmission.
In particular, this does funky things with Internet Explorer’s output. Last year I spent a few hours trying to figure out why borders around my buttons were extending by one pixel both down and to the right, until I realized that on the actual PC’s display this wasn’t happening… it was just an RDC quirk.
With that out of the way, I have to admit that perhaps my current problem is an issue with RDC and not with Internet Explorer. But either way, it’s a Microsoft problem.
After making some CSS adjustments to a page I was working on, I noticed that the main body seemed to be extending 3 pixels wider than it should be. Further testing revealed this only happened on certain pages, and after resorting to commenting out each CSS class one-by-one, I tracked this down to an inline class that simply italicizes text. So, for whatever reason in the grand Microsoft scheme, a word or two in italics can cause a much larger section of the page (at least 2 or 3 levels up in the document tree) to expand by 3 pixels.
Again I ask… WHY???
And again my cry for explanation goes unheeded. Time for another lame workaround?
Addendum: As it turns out, in this particular case a workaround will not be needed. I went to our test PC and confirmed that this is an RDC glitch, and not an Internet Explorer one.
