I am using Excel 2000 on Windows XP SP2.
This is really dumb, but for the first time eveer I am trying to insert a hyperlink into a cell, and whatever i do (select text or a complete cell) the Insert Hyperlink button on the toolbar remains grayed out (disabled). Similarly does the "Insert Hyperlink" command in the Insert menu, and also the CTL-K hotkey does nothing.
A found a wierd solution: if I click Window | New Window I get a new window onto the same file, but this time Hyperlink is enabled.
What's going on? Seems like I've got a bug.
