Freeze When Link Current File in Favorites

Hi,

I'm using v5.4.5 and current version of Favorites plugin.  I'm having an issue that can be reproduced using the following steps:
1) Right Click on [Files] and create a New Group
2) Click the "Link Current File" button
3) Click the "Details>>" button
4) Double click on the "[Files}' list entry to show my new group, then select it.
5) Click OK
Result: CPU spikes to 100% and Notepad++ never returns control.  I have to kill Notepad++ using Task Manager, and lose all of the recent changes to my Favorites configuration.

Anyone know if there is a way to fix this issue? 

I can work around it but its rather slow and painful.  Workaround is linking the current file directly into "[Files]", right click the link, cut, right click the new group, then paste to move the link.  You need to do this individually for each link because you can't select multiple links at once. 

Also I'm rather surprised that you can't write click on a group and open all those files at once.  I know this probably overlaps with the session functionality but it seems a rather intuitive thing to try.

Thanks,
Matt
