I have some additional questions re my upgrade to Opus 11.
First, I made an apparently incorrect assumption. I selected to keep my settings from 10 when 11 got installed. But when 11 was fully installed, my screen display was totally different. So I had Opus 11 restore the OCB file I had created for 10 before the upgrade. That did give me some of the elements I had in 10, but did not give me all the options that I had selected in Opus 10. So I had to manually set them.
I guess this means that the OCB file does not really save all the settings in Opus.
Also, there is a strange situation regarding the keyboard shortcut for displaying the size of folder(s). In Opus 10 on my main machine, I could call for the size of a folder by putting the focus on that folder, and then hitting CTRL+L. And I could select multiple folders, and click on CTRL+L, and all the selected folders' sizes would be calculated and displayed almost instantly.
Opus 11 on my main machine also does same thing very nicely. All my desktops are running Windows 7 fully updated.
I just finished installing Opus 11 on my number 2 machine, which was running Opus 10. As I noted above, I used the OCB file from my number one machine, after Opus 11 was installed. And after I manually changed some settings that the OCB file did not restore, I checked to see if CTRL+L worked there as it did in my number 1 machine. It does not. If I highlight a folder, and then hit CTRL+L, it might or might not bring up the size. If I select a group of folders, and then hit CTRL+L, it might just show the size for one folder, of often not show sizes for any.
I have no idea what's going on here - but I guess I must be missing something. Is there a setting somewhere that I have overlooked?
