interface did not adapt well to the new paradigm of mouse and pull-down menus, especially with many of WordPerfect's standard key combinations pre-empted by incompatible keyboard shortcuts that Windows itself used; for example, Alt-F4 became Exit Program, as opposed to WordPerfect's Block Text. The DOS version's impressive arsenal of finely tuned printer drivers was also rendered obsolete by Windows' use of its own printer device drivers. WordPerfect Office Suite WordPerfect became part of an office suite when the company entered into a co-licensing agreement with Borland Software Corporation in 1993. The offerings were marketed as Borland Office, containing Windows versions of WordPerfect, Quattro Pro, Borland Paradox, and a LAN-based groupware package called WordPerfect Office. Originally based on the WordPerfect Library for DOS, the Novell / WordPerfect Office suite was integrated by "middleware". The most important middleware-suite, still active in current versions of WordPerfect Office, is called PerfectFit (developed by WordPerfect). The other "middleware" (developed by Novell) was called AppWare. Novell buys WordPerfect Company The WordPerfect product line was sold twice, first to Novell in June 1994, who then sold it (at a big loss) to Corel in January 1996. However, Novell kept the WordPerfect Office technology, incorporating it into its GroupWise messaging and collaboration product. Microsoft vs Novell Compounding WordPerfect's troubles were issues associated with the release of the first 32-bit version, WordPerfect 7, intended for use on Windows 95. In the lawsuit 'Novell v. Microsoft', Novell argued that these problems were due to anti-competitive acts by Microsoft. While WordPerfect 7 contained notable improvements over the 16-bit WordPerfect for Windows 3.1, it was released in May 1996, nine months after the introduction of Windows 95 and Microsoft Office 95 (including Word 95). The initial release suffered from notable stability problems. WordPerfect 7 also did not have a Microsoft "Designed for Windows 95" logo. This was important to some Windows 95 software purchasers as Microsoft set standards for application design, behavior, and interaction with the operating system. To make matters worse, the original release of WordPerfect 7 was incompatible with Windows NT, hindering its adoption in many professional environments. The "NT Enabled" version of WordPerfect 7, which Corel considered to be Service Pack 2, was not available until Q1-1997, over six months after the introduction of Windows NT 4.0, a year and a half after the introduction of Office 95 (which supported Windows NT out of the box), and shortly after
