*** Bug 216302 has been marked as a duplicate of this bug. ***
I've found that both Thunderbird and Firebird have a problem with their Cut/Copy/Paste commands when: (I) cutting/copying from these applications to another external application, and (II) cutting/copying/pasting internally. I've also found that attempting to cut/copy will erase whatever is on the clipboard. Pasting from and external source works. The three main venues for executing these commands have been attempted, namely (1) Edit Menu, (2) Right-click Menu, and (3) Keyboard Shortcuts. I am using Windows 2000, Thunderbird 0.3, and Firebird 0.7. I hope this helps.
I've tried version 0.4 on Linux (Mandrake 9.2 using Gnome 2.4) and Copy/Paste works if using the keyboard (Ctrl+C/V) but not using the menu. I have only encountered this error in the "View Message Source" (have not tried elsewhere). Hope this info helps.
The problem still exists using TB 0.5 under Windows2000. File menu operations do not work, but keyboard operations (i.e. Ctrl-C) works as expected.
Ctrl-A and Ctrl-C are but the only ones working. Finding text within a mail's source still doesn't work, whether tried via clicking Edit->Find, pressing Ctrl-F or typeahead find (which I miss most). There's no bug addressing problems with find. Does this one cover it as well or should I open a new one for that?
Scott just fixed this by checking in the fix for bug 233976. :-)
