Internet Explorer Cross-Frame Security Bug Patch -- Microsoft has announced a potential security problem affecting Internet Explorer that could enable a Web site operator to access the contents of your local disks. Dubbed the "cross-frame navigate" issue, the problem affects both Windows and Macintosh versions of Internet Explorer 3.x and 4.x. On the Mac, Internet Explorer 3.01, 4.0, and 4.01 are vulnerable although 3.0 is not; under Windows, any application (such as Eudora Pro) that can use Explorer's HTML engine could also be vulnerable. Microsoft has released a 2.3 MB updater for the Mac version of Internet Explorer 4.01 that fixes the problem; users of Explorer 3.01 and 4.0 must upgrade to version 4.01 and then apply the patch. Although little information is available, Microsoft claims to have no reports of anyone exploiting this loophole. [GD]
Find Text Leading from Acrobat PDF
Ever have to recreate a document from an Acrobat PDF? You can find out most everything about the text by using the Object Inspector, except the leading. Well, here's a cheesy way to figure it out. Open the PDF in Illustrator (you just need one page). Release any and all clipping masks. Draw a guide at the baseline of the first line of text, and one on the line below. Now, Option-drag the first line to make a copy, and position it exactly next to the original first line at baseline. Then put a return anywhere in the copied line. Now adjust leading of the copied lines, so that the second line of copy rests on the baseline of the second line of the original. Now you know your leading.
Or you could buy expensive software to find the leading. Your choice.
