Default PDF reader

For some time we’ve been doing our income-tax on fillable PDFs.
For example, we get a Form 1040 and Schedule A off the Internet as fillable PDFs, and then fill in on our ‘pyooter.
This gets into why the form isn’t self-calculating.
Seems it could be, but it’s not yet.
What we do is a penciled-in trial run, and then fill in the PDF from that.
It requires proofing, what we used to do when I filled it in by hand years ago.
There are two of us.
I do the PDFs, and then Linda proofs.
I have to keep the PDF open, since I can’t save the filled-in form, shut off, and fire up my filled-in PDF when I boot up.
Shut off, and I have fill in the entire PDF again — start from scratch.
If I made an error in transferring figures, my filled-in PDF has to be open to edit.
Can’t save it.
Maybe eventually the Feds will make the filled-in PDFs savable, like some of the N.Y. State forms are.
Gotta watch what your web search turns up, as often the PDFs are a prior-year tax-form. I saw one for 1997.
We had to jump through hoops to get 2008.
Federal income tax was done and filed some time ago.
That was because they owed us money.
I let the N.Y. State income tax wait, because we owed them money.
I filed it today (Wednesday, April 15, 2009; Tax Day).
Last night (Tuesday, April 14, 2009), I was filling in the N.Y. State tax forms, IT-150, etc.
We had to download a form — IT-2105.9.
What usually happens is the download asks -A) open with the default PDF reader, which is 5.0 (an antique); or -B) just save to desktop.
I just save to desktop, since I can then open the saved PDF with my current PDF reader, which is (was) 6.0.
I upgraded to 6.0 some time ago. Seems 5.0 was a hairball; didn’t support the fill-in function or something.
“That’s funny,” Linda said. “Seems when you upgraded that would make 6.0 the default reader.”
But it didn’t — or I missed something. (I had a stroke.)
With 6.0 on, I noticed a tab for upgrading to 7.0. “Why not? Do it now. It’s free!”
Oh, why not? I click the tab, and it wants to upgrade me to 9.0.
“Download now!” Boom-zoom. “Installing 9.0 on hard-drive.”
I still have 5.0 and 6.0; both of which I hope to toss someday.
Drag 9.0 application into “Dock;” vaporize 6.0.
Now the question is if 9.0 has become my default PDF reader.
If not, can I make it so?

(“9.0 is not your current default PDF reader. Do ya wanna replace 5.0 with 9.0?” YES!)

“PDF” is “Portable-Document-Format;” sort of a photograph of a document.

“‘Pyooter” equals computer.

“Linda” is my wife of 41+ years. She majored in college in English and History.

A “PDF reader” is a computer software application for displaying PDFs — mine is Adobe®.

“Save to desktop” is Personal-Computer lingo. A computer-file can get saved to various places; e.g. the computer’s “desktop;” the display you usually see.

I had a stroke October 26, 1993, and it partially destroyed my brain. I always say I’m running on what’s left (other parts still alive take up doing what the destroyed parts did). —My ability to stay on top of things is compromised.

The “hard-drive” is the major personal-computer storage medium — it’s magnetic.

The “Dock” is an Apple OS-X term (“OS-X” is Apple Computer’s most recent personal-computer operating system). A bar exists on one side (or bottom) of the computer desktop display, where software application icons are stored, and when mouse-clicked they fire up the software application. A frequently-used software application’s icon can be dragged out of the hard-drive folder, and added to the “Dock.” (It’s a fast way of firing up a frequently used software application.)
