On my website I recently added three suites of photos.
Upon each photo I made a map area on the top and on the left and right side, linking to the index page, the previous page and the next page, respectively.
In preview, and on Safari and Firefox from the net, these areas are invisible as intended. However, I received reactions from InternetExplorer users that the outlines of the areas were showing up on the screen as dotted lines.
When I experienced with graphic elements instead of map areas these were reported as showing up as solid lines. I, myself, checked on a public PC and the lines were indeed showing except under certain zoom settings. Macintosh users do not seem to have this problem. I have now removed the suites until the problem is solved or I have to redesign with visible arrows or whatever.
The original links to the three suites are temporarily covered until I’m sure that the problem for PC-users is solved.
You can link to one of the suites by clicking on the top of the photo on the index page.
In the suite the links on the first seven pages are area maps, on the following pages they are empty graphic fields.
Strangely enough, this morning I received a mail from one of the PC-users who had reported the problem. He said that the outlines had now disappeared. ???
I’m quite ignorant about PCs and Explorer, but if the disappearance is not a case of blurred morning vision, could it be an issue of settings in Explorer ?
Earlier today I did a test page with map areas (upper fields) and empty graphic fields (lower fields) for you to se any difference. Click on the left side of the index photo to see the page.
However, I got feed back today from PC users who said that the appearance/disappearance of the lines were related to primarily the screen size and to a lesser degree the zoom. I also borrowed an old PC with a very small screen; here even with 400% zoom the lines were not visible.
Anyway, due to the mess I decided to bin my original design idea and are now changing the pages with arrows instead as you also proposed.
