Bug reports

Reported bugs

This is a table of bugs that I have reported. The "Report" column contains an exact copy of the bug report, with some additional information. I have later found out that some bugs have been reported by others. (See the Note: header in the reports). The "Brief Summary" column usually contains the same text as the "Brief Summary" header in the reports. The "Links" column sometimes contain screen shots. Screen shots can be treacherous due to differences in monitor size and resolution. For this reason, I have provided a ruler to indicate what I see on my monitor.

Unreported bugs

This is a table of bugs that I have not reported, for various reasons. Those reasons include:

I should probably add a column stating the exact reason the bug has not been reported. I’ll mention it in the Note: section of the reports at any rate.

About

About this page

This page was created to collect the bug reports I have filed for the Opera web browser. I tend to use long and descriptive file names for my bug-reports, and the default interface for directory listings that my dial-up ISP provides, simply truncates file names that are too long. So, this page was badly needed.

The page is written in HTML 4.01 and CSS 2.1, and contain no scripts or other nonsense. However, IE 5.5 made such a mess of the page, that I found it necessary to use a CSS trick to save it from itself. Also, I have tried to sprinkle the page with 'id' attributes to facilitate linking and styling.

Known problems

The server does not send a 'charset=' parameter in the 'Content-Type' header. Apparently, this can’t be fixed because I’m using some crappy hosting that came free with my dial-up account. As I’m only using ASCII characters, this is not really a problem. However, I have plans to launch a real< 168 /em> site. If I finally get around to it, I’ll move this page to a real hosting service, so that this finally goes away.

The W3C’s CSS Validator complains about Line : 0 Property display doesn't exist for media. I’m told this is a bug in the validator.

There are some Opera bugs visible on this page:

  • The hyphens in the dates at the top of the page tend to have an incorrect vertical placement. (See: bug report 150174).
  • Some of the tooltip-like texts that appear when you hover over <acronym>s are so badly misplaced as to be invisible. (See: bug report 150175).
  • When un-hovering links inside the tables, traces of the outline tend to be left visible on the screen. (See: bug report 147604).
  • At one time, the page needed to be reloaded for all CSS rules to take effect. I don’t know what has changed since then.
