Diff files from the repository doesn't work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open a repository in svnX 
2. Select a file
3. Select 2 revisions that are non-sequential; example 43466 and 41978
4. Click Diff

What is the expected output? What do you see instead?
Should see diff of the two revisions 43466 and 41978. 
Instead I see a diff between 43466 and 43465.

What version of the product are you using? On what operating system?
svnX 1.3
Mac OSX 10.6
svn 1.6.13

Please provide any additional information below.

I think you are doing it wrong.
This changed in svnX 1.2.
Clicking Diff (cmd-D) now diffs against the PREV revision (no dialog) &
Alt-clicking Diff (cmd-L) diffs against a custom rev (via a sheet).
[Hover the mouse over the Diff toolbar item.]

Thanks for the fast response, 2 things:
1) Doesn't seem to work for me. I tried a cmd-L and an alt-click, neither bring 
up sheet.
2) Why have a multiple select list if that doesn't apply to Diff?

1. You have to select a target item in the repository browser (bottom of 
window) or an item path (from currently selected log list item) first.
2. To which "multiple select list" are you referring?
The log list is single-select.  The repository browser columns are 
multiple-select which works for Diff-PREV & several other commands.  For 
Diff-custom it uses only the first item in the selection.

Ok. I got it to work. I was double clicking a file and then it just shows me 
the revisions for that file in the upper half and just the file in the bottom 
half.  I would then click the revision I was interested in and cmd-L and it 
wouldn't work. If I click the file again at the bottom and cmd-L it works.

So even though the file is selected in the bottom of the window, if it doesn't 
have the focus, cmd-L will not work.

Thanks for your help.

Diff-PREV (cmd-D) works on log items, log item paths & repository items so it 
must look at the primary focus.
Diff-custom (cmd-L) doesn't work on log items, but needs to be consistent with 
Diff-PREV.

[Perhaps I should add a way to diff the currently selected log item or log item 
path with the current repo browser revision.
 Though for log items this would be a diff of the entire repo. (So should perhaps require user confirmation.)]
