Windows XP O/S.
Flash Professional, version 8.0
Where a copy of the file is located:
What the problem is:
When I open the file, and I double click on the text folder in the library, a movie clip named "Text 138" cannot be edited because I get this warning message. Basically what happens is if I click "no" then the editing feature does not open. If I click "yes" then for a while it allows me to make changes to the movie clip, but then Macromedia Flash crashes, and I can never open that .fla file again, until I re-download the file from scratch.
Here is the interesting part. Although the header.fla file crashes Macromedia Flash after the initial load-up, if I try to open Macromedia Flash on its own, there is no problem.
