Numerous people have reported in the past, that the Shift key does not freeze the Word Analysis Window when using BibleWorks 7 or 8 on Parallels 6, 7 or 8. This bug has been present since at least 2008 (
see posts here,
here and
here) This does not happen when running BW in VMware or VirtualBox. Looking through the BW forums it was suggested to use the Option/Alt key as a work around. I used this for months, but was never satisfied with it as you had to click the Browse Window again to continue updating the Word Analysis Window.
While looking for a solution in the Parallels forums, I found out, that the bug is caused by a faulty way of handling the Shift Key in Parallels Desktop. It is a known issue as admitted by Parallels
staff: "PD delays shift until other key is pressed as it is a part of some shortcut which should not go to VM." Even though promised by them this has never been fixed in the default installation of PD, as I still had the problem after upgrading to PD8.
There is a simple solution, though, which I have not seen mentioned in the BibleWorks forum. Just change the settings for your VM as follows: In the Parallels Desktop menu go to 'Virtual Machine' --> 'Configure...'. Then in the configuration dialog click on 'Options' then select 'Advanced' and then activate the Option 'Optimize modifier keys for games'.
I eventually found a Parallels Knowledgebase article with screenshots about this, which in spite of the title, also applies to BW:

I hope this helps someone. Please let me know, if it works for you.
