The three finger swipe left and right does not seem to work
Hi
I have been trying to do the left and right three finger swipe that allows you to move between applications to no avail. It just keeps switching between dashboard and one app even if I have 5 apps open at the same time. Snow Leopard has this feature where all the apps opened are shown when you do the swipe and you can choose the one you want. I think this is better but it doesn't work.
Any help will be appreciated.
Antonio
Such spaces actually use very little extra memory relative to the apps you have open to occupy those spaces. I would go out on a limb and say it doesn't matter whether you have one space for every application or all on the same desktop.
The limitation will come from the applications and the data you are crunching on them.
(But that's just a personal view, haven't run into any limits on my ow 4GB Macbook Pro so far)

My iMovie 11 movie has clips that have some extracted audio that I would like to use for the menu music in iDVD 11. Does anyone know how to do this? Copy and paste does not seem to work.
I would use Quicktime Pro.

With Windows 7 I upgraded itunes to 11. Now in my itunes library, when I click on a song "original file could not be found" comes up. This happens with over 2000 songs, but it seems to be ones I recorded from cd's. Locate does not seem to work. Has anyone else had this problem?
Highlight a song that is supposedly missing, press CTRL+I to Get Info, say no when asked to locate the file, then look at the summary tab. Where does iTunes "think" the file should be? Where is it really? You may need to give a configuration file a minor tweak.

DBMS_TYPES with timestamp and interval does not seem to work.
I have a PL/SQL script that seems to work for char,varchar,numerics, dates, but not for intervals. I basically took example code out of the Oracle manuals and stitched it together.
The code in question is the function colTypeString. Apparently, interval is not being recognized as a type, so the function is returning back unknown. The documentation seems a bit spartan, so I thought perhaps you can help me out.
Thanks.
Here's the code:
create table interval_test( intym interval year(4) to month, intdm interval day(3) to second(4) );
execute oraforum_pkg.desc_query( 'select * from interval_test' );
col_type = 182, UNKNOWN_TYPE
col_maxlen = 5
col_name = INTYM
col_name_len = 5
col_schema_name =
col_schema_name_len = 0
col_precision = 4
col_scale = 0
col_null_ok = true
col_type = 183, UNKNOWN_TYPE
col_maxlen = 11
col_name = INTDM
col_name_len = 5
col_schema_name =
col_schema_name_len = 0
col_precision = 3
col_scale = 4
col_null_ok = true

user554561The issue is that DBMS_SQL and DBMS_TYPES have different typecodes. Which means you can't interrogate the DBMS_SQL.DESC_REC using DBMS_TYPES constants. You could create yourself a package of DBMS_SQL_TYPES.

Which functions do you want to perform with those gestures?
You can assign function to the related browser.gesture prefs on the <b>about:config</b> page.
To open the <i>about:config</i> page, type <b>about:config</b> in the location (address) bar and press the "<i>Enter</i>" key, just like you type the url of a website to open a website.<br />

I bought my daughter a new MacbookPro 13" for grad school and selected the HP Envy 100 printer from the Apple Store website. When I just tried to install the printer, it said that that the software was not compatable with Lion. Any suggestions as to how to get it to work?
Sorry, but the response just takes you to the HP site which is of all possible assistance short of actual help!!
HP (and Apple?) need to fess up and tell all the people who have HP printers when they will "just work" with their machines and OS X Lion.... because for many of us, they just don't! It isn't rocket science guys.... blithely telling us that downloading S/W updates from Apple doesn't help.... because they don't solve the problems! -

%rowtype and %type does not seem to work for 8i
Hello,
I have tried to define a package and in the package
specification I have defined
type abc is ref cursor return qq%rowtype;
The table qq exists and I can see it, insert into it.
I have got an error, when I declare a procedure with
formal parameters using %type inside a package specification.
After changing %type to number I can compile.
When I declare an anonymous block with %rowtype definition I am fine.
According to the documentation %rowtype and %row are allowed in packages. Is it a well known bug?Do you have direct grant on the QQ table or is it role based?
Role based access is not recognized in PL/SQL stored procedures. -

HT1338 My new magic mouse will not one finger scroll left and right
I am up to date with software but after connecting my new magic mouse it will not one finger scroll left and right. It does scroll up and down. Any ideas on what may be wrong??
I don't have a Magic Mouse, but there is probably a setting that enables and disables horizontal scrolling. Look on System Preferences Mouse pane.

The three finger swipe gesture works fine within Windows and in other browsers, but in Firefox (which is my primary browser) it doesn't seem to work.

There are a few Firefox add-ons that may work for you. Give these a try:

Can articles swipe left and right?
Is it possible to have articles swipe left and right instead of just up and down? From what I can see at the moment you swipe up and down in an article (multiple pages of course) and swipe left and right to change articles. I am trying to publish a gardening magazine and it has many 2 page images. When swiping and down they flow poorly.
Set them to horizontal swipe only in the article properties.
