"...The complaint describes how Microsoft is abusing its dominant position by tying its browser, Internet Explorer, to the Windows operating system and by hindering interoperability by not following accepted Web standards..."

Just when it seemed like Microsoft's European anti-trust tangle on browser choice in Windows was over, trouble is stirring again. Opera Software has told The Reg that it has informed the European Union of a possible problem with a fix that was designed to make Internet Explorer in Windows comply with EU antitrust law. Opera has also informed Microsoft.

With recent news about Internet Explorer 8's imminent beta, Microsoft's long and checkered history with web standards compliance has been hurled back into the harsh, unflattering spotlight. Even though IE8 will have a new "standards compliant" mode, it won't be perfect, stirring up a new wave of grumbling about Microsoft's attitude and position in the browser market.

"Following its investigation of Opera Software ASA’s antitrust complaint, the European Commission confirmed today that it sent Microsoft a Statement of Objections yesterday, accusing it of illegally tying Internet Explorer to the Windows PC operating system..."

As many believe, web users and innovators emerged winners upon the completion of the European Commission’s investigation into Microsoft’s browser-bundling practices. Microsoft will now offer users of Windows XP, Windows Vista and Windows 7 a screen presenting a choice of Web browsers.

Opponents of that proposal, including Mozilla and Opera, have criticized the fact that the ballot screen is found within Internet Explorer, which is still bundled with Windows, and the fact that any alternative browser must be downloaded, which many users will be too lazy to do. So why are Mozilla and Opera being so reticent in the wake of the European announcement?

Microsoft may have won a year-long quest to make its Office Open XML document format an ISO-recognised international standard, but claims of foul play in the voting process may come back to haunt the software giant when the European Commission concludes its latest antitrust investigation of Microsoft's business practices.

Those of us who remember the word Netscape will also remember the browser wars. Then microsoft spliced internet explorer into its operating system and set itself up for one of the most publicised antitrust cases of this century.

" 'Microsoft should be required openly, fully and faithfully to implement free and open industry standards,' is the message of a letter by the Free Software Foundation Europe (FSFE) to European Competition Commissioner Neelie Kroes. To help achieve this goal, FSFE offered its support for a possible antitrust investigation based on the complaint of Opera Software against Microsoft. The complaint was based on anti-competitive behaviour in the web browser market..."
