Getting trapped in focus mode!?

[Zil]

I'm pretty sure this is the right place to ask this question...

So every once in a while, when I take my finger of the shift key, my computer makes a beep sound and my character does not unfocus. I have to press shift again a couple times in order to get back to normal movement.
I've been putting up with it 'till now, mainly because it hardly ever happens, but it just denied me a flawless Kanako run :trollface:

This is somewhat less important, but I just watched a replay in TD, and it kept desynching in every stage. I believe it happened whenever I died.

A third thing, and this has nothing to do with Touhou, whenever I type on this site, instead of automatically dropping to the next line when I reach the end of the box,
the screen just expands and shifts to the right, leaving the toolbars and such behind.

Help with this stuff would be nice...

It's not sticky keys. I'm pretty sure it's not anyway, since I diasabled that ages ago, back when I used to play Maplestory. 
EDIT: Yeah, it's not sticky keys, I checked. I was trying to force it to happen but I couldn't. It seems totally random. I can't even tell what triggers it.
Thanks for the quick reply btw

It sure sounds like sticky keys. They use the shift key and do make a beep. I'd check it anyway, can't hurt, and won't take more than a minute.

Easier way to navigate to it is to type Sticky Keys in the search box, then Change how your keyboard works.

I have mine like this here in Win7 and have never had any problems with shift.

No, it 100% for sure is not sticky keys; I checked it. I realize what I said there sounded missleading. The thing I was trying to "force to happen" was the shift glitch itself. I pressed shift like a maniac, moved all over the place, fired randomly, and I couldn't trigger the glitch. Sticky keys is off, I've checked a bunch of times.

Could it be your keyboard being glitchy?  Have you tried playing with a controller for comparison?

It probobly is my keyboard, but I'm not sure what I can do about that. I feel like using a controller would be a zillion times more difficult. This is something like a playstation controller we're talking about right? I just can't imagine using it.
This just occured to me: It has never happened in PoFV, no doubt because I use the "focus while shooting" setup, so I don't have to mash the Z button. So I don't focus with shift in PoFV. This seems to mean two things to me:
1. The problem is with the button itself, not the games or something like that.
2. I can possibly avoid it by using the focus while shooting option in the other games, though that may affect my ability to actually play them...

Huh, I thought that using a controller would actually be easier to use, with less problems or lag.  Since keyboards have a tendency to have weird rollover issues, especially cheap ones.

The problem I was thinking of with a controller is that I can't have a finger on every button; all the movement buttons would be pressed by the thumb, meaning it would be hopping to and fro like a thing possesed. Basically, I feel it would take half a second to change direction, and moving diagonally would also be a pain. I used to play Gradius on my PS2 way back when, and the controller always annoyed the hell out of me.

EDIT: Tried SA with focus while firing... entirely out of the question.
