When I click on an existing hyperlink and launch the Hyperlink dialog, I can make whatever changes I want, but I can't save the changes. When I click "Ok" I get an error beep. The only way to get of the dialog is the press Cancel and the only way to modify the hyperlink is to do it manually in the HTML view, which I have other problems with (the spacing is odd so I can't see all the characters around the cursor. It's pretty miserable.)
What's going on?
I thought maybe it was something related to not checking out all the files for the directory, maybe something associated with the files wasn't writeable, but most recently I decided to test it by checking out all the files, recursively, and it still didn't work.
An error beep only? No error message or anything?
As for your spacing, is the zoom level set to 100%? If not, try setting it to 100%.
Have you tested this in a new blank project ? If not then try to create a new blank project and insert hyperlink and see what happens when you try to edit it ?
