I don&#x27;t recall that, not even allegations to the effect (there were such for Office competitors), plus I probably would have learned of such while working with a guy who had previous interned at Microsoft on IE of that era.<p>More directly, I&#x27;m not aware of any public Windows APIs that handed out data that tricked your code into doing a general protection fault (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;General_protection_fault" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;General_protection_fault</a>), or in the case of WordPerfect, compel programmers to use their own printer drivers, and write code that regularly drops your tables, figures, etc. to the bottom of your document (unlike the other companies I cited, WordPerfect actually managed to ship a Windows version that didn&#x27;t GP fault, but that was late, terribly buggy, and prompted all the WP fans I knew to reluctantly switch to MS Word).
